Comparison of PEFR and FEV1 in Patients with Varying Degrees of Airway Obstruction: Patients with FEV

A further analysis was made by evaluating the data over the range of pulmonary function (Table 2). For patients with FEV! values of less than 50 percent predicted, the mean SD between the three efforts was 3.30 for FEVX compared with 5.47 for the JPF, and 4.67 for the WPF. Similar differences are noted in […]

Gonadotropin-Releasing Hormone Antagonist: DISCUSSION

Several studies performed in rats have demonstrated the in vivo or in vitro antigonadal effects of GnRH analogs. In previous studies, we have demonstrated that GnRH-a treatment produces a failure in the steroidogenic luteal capability and an increase in the apoptotic process in the ovary, eliciting consequently an interference in the follicular recruitment, growth, and […]

Gonadotropin-Releasing Hormone Antagonist: RESULTS

Morphological Studies Prepubertal rats were superovulated with eCG (control group, C) and treated with LA (LA group; 1 ^g rat day during 48 h), or Ant (Ant group; 10 ^g rat day during 48 h), or both (LA + Ant group). When the GnRH-agonist, LA, was injected alone, the ovarian weight decreased by 0.5-fold, whereas […]

Gonadotropin-Releasing Hormone Antagonist: MATERIALS AND METHODS

Hormones and Reagents The GnRH-a leuprolide acetate (Lupron), was a donation from Abbott Laboratories (Buenos Aires, Argentina). The original ampoule (2.8 mg/5 ml) was dissolved in saline solution. SYNTEX S.A (Buenos Aires) generously provided eCG (Novormon). HEPES, SDS, Antide [W-Ac-D-Nal1, D-pCl-Phe2, D-Pal3, Ser4, Nic-Lys5, D-Nic-Lys6, Leu7, Ipr-Lys8, Pro9, D-Ala10NH2; Nal-Lys antagonist] was purchased from Sigma […]

Gonadotropin-Releasing Hormone Antagonist: INTRODUCTION

In the mammalian ovary, only a small fraction of oocytes ovulate during reproductive life, whereas the majority of ovarian follicles undergo atresia by a hormonally regulated apoptotic mechanism. Gonadotropin-releasing hormone (GnRH) and its analogs have been widely used to prevent the spontaneous LH surge in assisted reproduction techniques. Suppression of gonadotropin secretion can be achieved […]

A guide to contraindications to childhood vaccinations

The infant and childhood immunization program in Can­ada has led to extraordinary decreases in serious infec­tions with diphtheria, tetanus, pertussis, polio, Haemophilus influenzae type b, hepatitis B, measles, mumps and rubella. There is a danger that this successful immunization program may lead to complacency about vaccine preventable illnesses such that parents, and sometimes physicians, may […]

Nonceliac diaphragm disease of the duodenum: DISCUSSION

The differential diagnosis of small intestinal ulceration and stricture formation is extensive. This is generally classi­fied into broad groups such as congenital, mechanical, in­flammatory, vascular, neoplastic and miscellaneous. Most formations are self-evident from clinical history and are rare. Granulomatous disease, especially with broad-based stric­tures, raises the possibility of Crohn’s disease or an in­fection such as […]
