THAT the corpus luteum plays a part in determining the reactivity of the uterine muscle at various stages of the sex cycle in certain animals seems to be definitely established. In the rabbit this has been shown by the direct injection of extracts, while in the human subject the lack of reactivity to oxytocin during the later stages of the intermenstruum and during the early stages of gestation are, according to Knaus [1931], also referable to the luteal function. On the other hand, such a mechanism does not appear to exist in the lower rodents, for in these animals the administration of a potent luteal extract does not abolish the uterine reactivity to oxytocin [Siegmund, 1930 a], and, moreover, the uterus apparently responds to the posterior lobe hormone during the whole course of gestation [Siegmund, 1930 b]. Now previous studies in the rabbit and on the human subject have shown [Rob son, 1933 a, b] that, in as far as the reactivity of the uterus to oxytocin is concerned, pregnancy can in both these species be divided into two stages, namely: 1 ; a period during which the uterus shows no reaction whatsoever even to large doses of oxytocin, and 2 ; a subsequent period during which the reactivity to oxytocin returns and gradually increases up to parturition at which it attains a maxmum. The development of reactivity during the second part of pregnancy does not appear to be dependent merely upon the withdrawal of the luteal secretion [Robson, 1934] and may to some extent at least be due to the action of cestrin [Robson, 1933 c].

Cassady represented for the Pranksters an ideal of thought and action fusing into a vibrant whole, into pure up-front being. They assumed that whatever was inside a person would come out during the trip LSD had a way of making this happen everyone agreed this did not mean that whatever spewed forth would always be beautiful and lovey-dovey. Weird behavior was commonplace on the bus, and awards were given out regularly for "Most Disgusting Trip." The idea really was to go "furthur, " to explore the unknown, to feel no limit as to what might be discovered and expressed on acid. It was in this sense that a mission was taking shape among the Pranksters. It had nothing to do with the salvation of the world; it was more a feeling, a "synching" together that created an atmosphere of "creeping religiosity." As a group they searched for a unified consciousness that would outstrip once and for all the pseudo-reality they had left behind and paclitaxel. Send reprint requests to: Dr. Keith W.

Erly used may help reduce the discrepancy between the experimentally obtained and theoretically calculated milk-to-plasma u]trafiltrate ratios. I t still must be pointed out that the mechanisms of secretion of weak organic acids into milk must be studied under equilibrium conditions, as oxytocin treatment did not completely eliminate this lag. Milk-to-plasma ratios in the trials when oxytoein was given did not show sufficient agreement with theoretical ratios for passive diffusion to make the method useful for studying the mechanism of drug transport. The remaining lag may be due to the actual time required for the drug to pass across the membrane. Weak organic acids having high p K , values tend to diffuse more rapidly into the milk than acids with low p K , values. Stowe et al. 16 ; showed that sulfacetamide pKa 5.4 ; passed into milk more slowly than sulfamethoxypyridazine pKa 6.7 ; . I n this study it appears that sulfacetamide reaches a peak concentration in milk much later than does sulfamethazine. The rate at which the peak concentration appears in the milk seems to be dependent upon the amount of passively diffused drug in the un-ionized form. A greater proportion of the sulfamethazine will be found in the un-ionized form. The more lipid soluble drug may also reach a peak in the milk much faster than the lipidinsoluble drug. This is logical when one considers that the un-ionized lipid-soluble portion of the drug molecule can dissolve in the lipid layer of the membrane and pass across this membrane [Jacobs 5 ; and Davson and Danielh 3 ; ]. Schanker et al. 12 ; , as well as Holder and Haynes 4 ; , showed that the more highly lipid soluble organic acids pass into human red cells much more rapidly. Schanker et al. 12 ; showed that phenol, sulfathiazole, and sulfadiazine diffuse more rapidly and are relatively lipid-soluble as compared to p-aminohippuric acid, which is relatively lipid-insoluble. The chloroform to water partition coefficient was found to be 23, 000, 1, 040, 441, and 0.031 10~ ; for phenol, sulfadiazine, sulfathiazole, and paminohippuric acid, respectively. More refined studies must be carried out to determine the effect of pK~ and lipid solubility on the lag period, as expressed by the time it takes for peak concentrations to appear in the milk as well as the difference between theoret: ical and actual milk-to-plasma ultrafiltrate ratios.

Ms Mafumo was asked to follow-up on how far was Mr. Piet Steenkamp with the process of compensation. Landowners around the substation must be consulted in one all inclusive meeting so that all stakeholders can share ideas and understand each others problems and concerns regarding the proposed development. It was agreed that representatives from Uitval Grond Owners; Rankotia and Bakgatla BaMakau both members of the Traditional Council and Private Owners ; be invited to the meeting. The location of Eskom Construction camp in the area near the cemetery was never discussed with the present traditional council. The council think that this might have been negotiated with someone else. The council will make a follow-up on who gave Eskom permission to build the camp. This was later found to be an Eskom Distribution camp. The meeting agreed that Mr. M. P. Sekgothe accompany the PIP Team to Rankotea to go and meet the leader of the Krokodilkraal Co-owners Committee. The meeting took place with the co-owners represented by Mr. Adolph Modeselle and Ms Hendrietta Poo see attendance register ; o The project and the recommendations made by the traditional council were explained. The purpose of the meeting was therefore as a result of the council suggesting that stakeholders around the substation be consulted. o The map as discussed with the co-owners showed that the Bakgatla BaMakau are not affected. The Bakgatla BaMakua will however still be kept as stakeholders since their farm Hoekfontein is adjacent to Krokodilkraal on which the Dinaledi substation is situated. o Mr. Modeselle raised a concern that Eskom constructed an access road to the substation. This road goes through their land and they were never consulted and compensated. o There is also a concern about the supply of electricity in Rankotea in that the two lines feed the area and one line constantly fails. Mr. Modeselle wanted to know if the substation upgrade and the new transmission lines will improve the situation. [Mr. Mahlangu mentioned that though and paromomycin. Particularly, the rat study ties in with the fact that there is a massive surge of oxytocin in males after experiencing an orgasm.
IGF-I availability; 4 ; a role for the androgen receptor in early bone development; 5 ; reduced supplementation with aromatizable androgens, which provide substrate for estrogen synthesis in situ; and or 6 ; more severe inactivation of androgen-receptor function 135, 223, 238 ; . Supraphysiological amounts of aromatizable and nonaromatizable androgens stimulate osteoblast proliferation, antagonize the osteoclast-activating effect of PTH, and elevate markers of bone growth 228, 241244 ; . In experimental animals, 5 -DHT especially stimulates periosteal appositional ; skeletal growth and thereby increases cortical bone formation 228, 245247 ; . However, available data are not facile to interpret, because 5 -reduced products of testosterone activate the androgen receptor and simultaneously impede estrogen action in some tissues 248 250 ; . In the human, the androgen receptor may mediate up to 30% of sex steroid-induced skeletal remodeling, as inferred by combined administration of a down-regulating dose of a GnRH agonist, testosterone, and placebo, or an aromatase-enzyme inhibitor in healthy older men. In the sex steroid-depleted setting, transdermal repletion of testosterone or estradiol alone suppressed indices of bone resorption, increased markers of bone formation, and stimulated production of osteoprotegerin, a potent inhibitor of osteoclastogenesis below ; . Each of the effects of testosterone was blunted by pharmacological aromatase blockade, with the exception of and pbz. Ciglitizone-induced initial [Ca2 ]i increase in myometrium and leiomyoma. The two primary pathways for obtaining stimulus-increased levels of [Ca2 ]i in smooth muscle cells are release from sarcoplasmic reticulum stores and an influx from extracellular space 23 ; . The increased [Ca2 ]i levels observed in myometrium and uterine leiomyoma could be from the sarcoplasmic reticulum. Release of Ca2 from intracellular stores into the cytoplasm occurs through two classes of Ca2 release channels, IP3 receptors and ryanodine receptors, which may or may not coexist, depending on the tissue 5 ; . Several mechanisms of intracellular Ca2 mobilization are present in uterine myometrium. However, in human uterine myometrium only IP3induced Ca2 release has been extensively studied to date 27 ; . The presence of functional ryanodine receptors was also established, and cADP-ribose served as an endogenous regulator for human myometrial Ca2 regulation 10, 34 ; . Although IP3-mediated Ca2 release by a contractant such as oxytocin is a popular mechanism for increasing intracellular Ca2 in myometrium 27 ; , this type of Ca2 release was not involved in this ciglitizone-induced [Ca2 ]i experiment. This study observed that the ryanodine receptor blocker dantrolene sodium completely suppressed the ciglitizone-induced initial [Ca2 ]i increase, whereas the IP3-receptor blocker U-73122 did not have an effect on the [Ca2 ]i response. These results suggested that the pathways of ciglitizone-induced initial [Ca2 ]i increase are the ryanodine receptors of the sarcoplasmic reticulum in human uterine myometrium and leiomyoma. In this study, the initial [Ca2 ]i increase induced by ciglitizone was inhibited by raloxifene, but the secondary [Ca2 ]i increase was attenuated by the PPAR- antagonists. These findings suggest that ciglitizone induced a rapid initial [Ca2 ]i increase via estrogen receptors and that this response was inhibited by raloxifene. Recently, Houston et al. 16 ; were the first to demonstrate that ciglitizone inhibits cell proliferation stimulated by estradiol and that stimulation of PPAR- signaling also inhibits estrogen receptor-mediated gene expression of vit-ERE-Luc reporter and progesterone receptor A. The results are supportive of a functional interrelationship between PPAR- and the estrogen receptor. The present study also showed that ciglitizone induced the initial [Ca2 ]i release from the sarcoplasmic reticulum through estrogen receptors in uterine leiomyoma, as shown in Fig. 3B. Ciglitizone-induced SOCC activation in human uterine leiomyoma. Despite the same initial [Ca2 ]i increase in both types of cells, the ciglitizone-induced secondary [Ca2 ]i inFig. 5.

Isolated uterine strips from similarly treated rats showed a reduced maximal contractile response to oxytocin and an elevated k m value, possibly indicating an influence of oxytocin on the coupling between receptor occupancy and contractility and pediatric.
Found to have conjunctival erythema and potential periorbital infection. The intolerance subsides quickly on discontinuation of the therapy.83 CONCLUSIONS New topical agents for the treatment of glaucoma offer significant promise, both in terms of efficacy and in the absence of systemic events. Nevertheless, topical blockers are currently the most commonly used therapy for glaucoma. Therefore, increased communication within the medical community is warranted. Careful attention on the part of the primary care physician to the systemic effects of topical -blockade is paramount for several reasons. These medications must be remembered and ordered correctly on inpatient orders. Many hospitalized patients are treated for glaucoma, yet a small retrospective survey found that as many as 37% do not receive the correct medicine or amount.84 Recognizing the importance of these medications can help to ensure that their use is not indiscriminately discontinued without communication with the prescribing ophthalmologist. And, finally, these topical medications may partly or wholly explain an alteration in a patient's systemic condition. Conversely, ophthalmologists can benefit from consultation with the primary care physician to refine the choice of agents for certain patients. Ultimately, more studies and new agents may provide clear-cut guidelines for patient prescription; in the meantime, however, it is critical that ophthalmologists and primary care physicians communicate about the safest, most efficacious usage of such medicine.

And the quality of resulting analgesia was described as good. Seven hours later labour had failed to progress, in spite of oxytocin augmentation and it was decided to deliver the fetus by caesarean section. Anaesthesia was not adequate for caesarean section so a topup injection of 2 ml plain bupivacaine 0.5% was given from a 20-ml syringe. The spinal block spread higher than expected. The woman experienced difficulty breathing and then lost consciousness. She developed a bradycardia of 30 bpm and the systolic blood pressure decreased to 60 mmHg. The patient was intubated promptly and given fluids, ephedrine, atropine and adrenaline epinephrine. Cardiac output was restored but the blood pressure had increased only to 80 mmHg systolic when the baby was born apnoeic and pulseless. The paediatrician had not arrived and the anaesthetist was asked to intubate and resuscitate the baby. By the time the anaesthetist had completed the resuscitation the obstetrician had discovered an adherent placenta and the mother was losing blood. The obstetrician requested oxytocin Syntocinon ; to improve uterine tone. The anaesthetist was reluctant because the systolic blood pressure was only 60 mmHg. After rapid infusion of intravenous colloid solution and further adrenaline epinephrine, oxytocin 10 iu was given. Cardiac arrest occurred almost at once. Resuscitation followed accepted practice but was unsuccessful. High spinal block, bradycardia and hypotension are recognised complications of spinal anaesthesia. The cardiovascular complications involve complex reflexes1 that are still not widely understood. They are sometimes difficult to treat, especially when drugs with cardiovascular side effects further complicate the clinical picture. Whether the use of hyperbaric bupivacaine would have limited the cephalic spread and avoided the high block is questionable. The literature would suggest not. However, using a 20-ml syringe to measure a 2-ml does not ensure great accuracy. Syringes of 2-, 3- or 5-ml capacity are available and employed because additional fractions of a millilitre of bupivacaine can affect the extent of a subarachnoid anaesthetic. In this case, the patient was initially resuscitated effectively but the hypotension was not completely reversed when the anaesthetist was asked to resuscitate the baby. At the time the maternal blood pressure was 80 mmHg systolic. The baby was resuscitated quickly and effectively. However, the anaesthetist's full attention was distracted from the mother. In that time, the maternal systolic blood pressure had decreased to 60 mmHg. Uterine hypotonia occurred and the obstetrician asked for 10 iu oxytocin to be given. This is a common obstetric request during caesarean section. The administration of oxytocin in the presence of a high spinal block, hypotension and recent bradycardia, accompanied by bleeding at caesarean section, produced a situation from which the patient could not be rescued. Oxytocin has peripheral and central cardiovascular receptor sites and complex cardiovascular actions.5, 6 It is not widely appreciated that the dose recommended in the British National Formulary2 and other formularies3, 4 ; is 5, not 10, units.

In vitro transfection studies Initially, 4.5 104 cells of MDA-MB-435 cells were plated into a 24-well plate. After 48 h, when the cells were 60 and 80% confluent, cells were transfected with a plasmid-encoding luciferase PCI-luc ; . In transfection experiments, the co-polymer was initially incubated with 0.75 g of PCI-luc for 30 min in OptiM. The amount of co-polymer varied from 0.06 to 7.5 nmol. Then, 1.5 g 2.15 nmol ; of cationic liposomes were added to the polymerDNA mixture, and allowed to stand for an additional 30 min. The total volume for the polymer liposomeDNA complex was 120 l. The polymerliposome DNA complex was then diluted with either 200 l of OptiM or OptiM + 15% serum. In experiments with lysosomotropic agents, bafilomycin A1 Sigma ; was added to the medium at concentrations of 10 ng ml. Four hours after transfection, the complexes were removed and DMEM with 10% serum was added. Forty-eight hours later, luciferase levels were measured with the direct current TD 20 luminometer Turner Design, Sunnyvale, CA ; as previously described. Relative light units were converted to protein pg ; of luciferase with recombinant luciferase Promega, Madison, WI ; as a standard. Duplicates were done for each concentration and each experiment was performed twice. Measurement of particle size of polymerDNAliposome complexes PCI-luc 2 g in 200 l of 10 HEPES pH 7.4 ; was mixed with 21 nmol of linear polymer or 1.05 nmol of branched polymer in 200 l HEPES for 30 min. Then, 7 g of liposome in 200 l HEPES was added for another 30 min. After adding 1900 l of HEPES to the complexes, a total volume of 2.5 ml was used for the measurement, which was carried out with a N4 Submicron Particle Sizer Coulter, Miami, FL.

Understand their psychological impact. For this reason, we obtained and are analyzing data from a substudy of SCDHeFT addressing this issue. We also agree with Dr. Ahmed that a collaborative model of treatment should be used in all patients with congestive HF. It is thus important that primary care physicians including gerontologists ; understand that patients who are still symptomatic despite treatment should be referred to a specialist in HF regardless of the patient's age. One can debate Dr. Ahmed's assertion that depression is more common in the elderly; the data he references suggest that major depression is less common, whereas "minor" depressive symptoms may be more common 4, 5 ; . The current study involved many patients under age 65 years, dictating use of an instrument appropriate for a broad age range. However, we do not consider determination of the exact prevalence of depression in various groups as the important result of our study. Rather, our findings emphasize the difference in patterns of depression between patients with severe HF and the general population. Furthermore, we demonstrated in the wide range of patients studied ; that depression, as quantified by standard questionnaires, was extremely common in all groups. In our sample, 53% of those under age 65 years and 43% of those age 65 years and older reported symptoms of depression. As Dr. Freudenberger and colleagues are well aware, the interaction of depression and symptoms of HF is complex; three of the co-authors of our manuscript S.S.G., M.L.F., S.R. ; coauthored a publication with two of them R.F., C.S. ; , which demonstrated that patients with depression believe themselves to be more ill even when there are no objective criteria supporting this perception 6 ; . Furthermore, as Dr. Ahmed's letter points out, diagnosis of depression is affected by many variables, including age, gender, and race. Indeed, any diagnosis of depression is, by definition, arbitrary. Thus, determination of the exact prevalence of depression can be debated ad nauseam, leading to obfuscation of the important points: depression is common and diagnosis may be impacted by various demographic factors. Although it is unreasonable to expect all patients with HF to be screened by psychiatrists, the Beck-Depression Inventory BDI ; is an excellent screening tool, and awareness of the prevalence of depression can lead to treatment and improved quality of life. Dr. Freudenberger and colleagues are of course correct that physical components of the scales might be influenced by the physical limitations of HF. It is for this reason that we reported the various subscales of both the Minnesota Living With Heart Failure MLWHF ; and SF-36 questionnaires. Both the emotional and physical subscales of the MLWHF a disease-specific qualityof-life questionnaire ; exhibited extremely close correlations with the BDI. Similarly, various components of the SF-36, including those not influenced by physical limitations, strongly correlated with the BDI. Depression may contribute to symptoms in any HF patient. Treatment efficacy will probably vary based upon age, gender, race or other factors, and these variables need to be assessed when intervention trials are performed. We now know, however, that consideration of the possible impact of depression upon symptoms is essential for all patients with HF. * Stephen S.
