DLE was prepared from the minority of euglycemic CD-1 mice, previously injected with STZ, and was administered to hyperglycemic CD-1 male mice 1, 2 and 3 weeks after completion of multidose STZ. Mice treated with DLE derived from 2 x 10(7) (IX) or 10(8) lymphocyte equivalents (lymph.equ) were significantly less hyperglycemic than the saline treated controls (P < 0.001). The effects of DLE remained evident for more than 10 weeks after the final DLE treatment. Mice treated with DLE prepared from diabetic mice (hg DLE) developed a somewhat more rapid onset of hyperglycemia than the STZ treated control animals, although this effect did not achieve statistical significance (P = 0.1). This DLE was absorbed on a rat insulinoma cell line (RIN), which contains interspecies cross-reacting islet antigens, and compared to the unabsorbed DLE. Mice treated with hg DLE preabsorbed on RIN cells, showed a slower onset of hyperglycemia. DLE prepared from euglycemia mice and the RIN-absorbed fraction were equally capable of preventing hyperglycemia (P < 0.05). In order to determine whether the DLE effects were genetically restricted, DLE was prepared from BALB/c mice, normally resistant to the diabetogenic effects of multidose STZ, both before and after STZ treatment. STZ primed CD-1 mice treated with 3 weekly doses of 2 x 10(7) lymph. equ. of untreated BALB/c derived DLE, STZ treated BALB/c derived DLE, and STZ treated CD-1 DLE were all less hyperglycemic than the control mice, who received saline (P < 0.001). However, mice treated with CD-1 DLE were less hyperglycemic than the mice given BALB/c derived DLE (P < 0.05). These effects were relatively long-lived. Mice that were given the > 3,500 Dalton fraction of CD-1 DLE were significantly less hyperglycemic than either the control mice or those treated with the < 3,500 Dalton fraction of CD-1 DLE (P < 0.05). Effects remained evident for more than 3 months after the last dose of DLE. Pancreatic tissue from the mice treated with the > 3,500 Dalton fraction of CD-1 derived DLE revealed slightly more islets of a slightly greater size with less surrounding inflammation than either control mice or mice treated with the < 3,500 Dalton fraction of DLE

Objective: To review the scientific and clinical bases for effective patient counseling in contraceptive care. Data Sources: All articles and chapters in the Annotated Bibliography of Doctor Patient Communication of the Task Force on Doctor and Patient of the American Academy on Physician and Patient were searched and included. This is an expert-derived data base based on MEDLINE review from 1969 to 1994 and including expert-selected additions from PsychLit and a variety of other social science data bases, books, and reviews. Methods of Study Selection: Expert consensus was used from the Committee on Bibliography of the American Academy on Physician and Patient. Tabulation, Integration, and Results: The doctor-patient interaction is the main determinant of the accuracy and completeness of patient data, diagnostic accuracy, efficiency in the encounter, compliance, patient understanding of problems, and patient and physician satisfaction. Yet this critical skill is inadequately taught and practiced, with serious consequences for patient care and physican job satisfaction. Use of the 14 structural elements (preparing the environment, preparing oneself, observation, greeting introduction, detecting and overcoming barriers to communication, surveying problems, negotiating a priority problem, developing a narrative thread, establishing the life context of the patient, establishing a safety net, presenting findings and options, negotiating plans, and closing) and three functions (gathering information, developing a therapeutic relationship, and patient education) and their associated behaviors improves encounter results significantly. Other helpful activities are patient activation, facilitating partnership, review of findings and plans, eliciting and responding to patients' attitudes and emotions about contraception and fertility, and use of empathy and positive regard. Conclusions: The use of scientifically derived, empirically validated interview skills substantially improves outcomes in contraceptive and other patient education and counseling. Use of appropriate structure and functions of the encounter, patient participation and partnership, review of patient understanding and reactions, and relating to the patients' attitudes and emotions about the subject each improve the outcomes of contraceptive care

Although thyroid hormone is obligatory for the development of cardiac beta-adrenergic receptors, it is difficult to assign a specific role for the hormone in receptor ontogeny because beta-receptor expression is affected similarly in the adult. We have determined whether thyroid hormone plays a role in receptor development by evaluating alpha 1-adrenergic receptors, which in the adult are downregulated by thyroid hormone. Propylthiouracil given from gestational day 17 through postnatal day 5 caused significant deficits in the number of alpha 1-receptors and values resolved to normal in parallel with hormone level recovery. When propylthiouracil was administered later (postnatal days 11 through 15) only a transient deficit in alpha 1-receptor binding was seen; hyperthyroidism (triiodothyronine) could still evoke stimulation of receptor expression at this stage. The effects on receptor expression were distinguished from general effects on cell differentiation by examining alpha 2-receptors, which disappear over the first three postnatal weeks; delayed differentiation caused by propylthiouracil would slow the decline in alpha 2-receptors, whereas accelerated differentiation caused by triiodothyronine would hasten the decline. Instead, the effects were similar to those on alpha 1-receptors: perinatal propylthiouracil administration reduced, and neonatal triiodothyronine administration enhanced, alpha 2-receptor binding sites. Thus, thyroid hormone plays a role in the control of cardiac adrenergic receptor expression during a critical development period, with conjoint regulation of the multiple receptor subtypes present within the tissue. As adrenergic stimulation is important in maintaining cardiac function in the perinatal period, alterations of thyroid status during this period can be expected to result in abnormal reactivity and increased perinatal risk

A 34-year-old woman presented with cyanosis and a methemoglobin level of 23.2% after perineal application of a topical anesthetic cream containing 20% benzocaine. Many commonly used products contain high levels of benzocaine, and their use can lead to life-threatening methemoglobin levels. This case reinforces the need for stricter guidelines for product use and warning labels to alert consumers to this potential side effect of topical benzocaine-containing products sold over the counter

The case of a 35-year-old woman who reported to Siegel with abnormal and sometimes missing periods is recounted. The diagnosis was premature menopause

Siegel discusses the unusual case of Sandra, a diabetic woman who suffered from extreme multiple personality disorder. It seemed as though Sandra's many different personalities had varying blood sugar levels

A paucity of literature and educational materials addresses the mistreatment of nursing home residents. After serving as expert witnesses in the successful criminal prosecution of a nursing home corporation charged with involuntary manslaughter of two nursing home residents, the authors recognized the need to improve recognition and prevention of institutional mistreatment. This article will describe our involvement in post-trial advocacy efforts to improve the quality of care of nursing home residents through community education efforts

We investigated the relationship among chemosensitivity to drug-induced apoptosis in vitro, the presence of p53 gene mutations, and the expression of bcl-2 and bax proteins in B-cells from B-cell chronic lymphocytic leukemia (B-CLL) patients. Apoptosis was induced with a camptothecin analogue, 9-amino-20(s)-camptothecin, or a purine analogue, fludarabine. Cell death was monitored by propidium iodide staining and FACS analysis. Drug-induced apoptosis in B-CLL cells was p53-independent. Immunoblot analysis of bcl-2 and bax expression revealed a correlation between drug-induced apoptosis and the ratio of endogenous levels of bcl-2 to bax proteins. B-CLL cells with none to low bcl-2/bax ratios were drug-sensitive as compared to cells with intermediate to high ratios that were drug-resistant (P = 0.015). Prior to drug treatment, bax protein migrated as a single species of 21 kDa. Following drug-induced apoptosis, anti-bax specific protein complexes of 36-42 kDa were up-regulated. Using two-dimensional gel electrophoresis, bax complexes were disrupted under reducing conditions to reveal homo- and heterodimers of 18 and 21 kDa suggesting that disulfide interactions were required for complex formation. The de novo appearance of the 18 kDa anti-bax specific protein together with its increased expression in drug-sensitive B-CLL B-cells undergoing cell death suggests a role for this protein in the regulation of apoptosis
