Glyoxysomes of endosperm tissue of castor bean (Ricinus communis L.) seedlings were solubilized in a detergent and added to a lipid bilayer. Conductivity measurements revealed that the glyoxysomal preparation contained a porin-like channel. Using an electrophysiological method, which we established for semiquantitative determination of porin activity, we were able to demonstrate that glyoxysoma...

Leucine and glutamine were used to elicit biphasic insulin release in rat pancreatic islets. Leucine did not mimic the full biphasic response of glucose. Glutamine was without effect. However, the combination of the two did mimic the biphasic response. When the ATP-sensitive K+ (KATP) channel-independent pathway was studied in the presence of diazoxide and KCl, leucine and its nonmetabolizable ...

background: polycystic ovary syndrome (pcos) is associated with approximately 75% of women who suffer from infertility due to anovulation. additionally, around 20– 25% of anovulatory women with pcos do not respond at all to clomiphene citrate and are considered to be “clomiphene– resistant”. aromatase inhibitors have been suggested as an alternative treatment to clomiphene as the discrepancy be...

The effects of aluminium and aluminium-citrate on some serum parameters related to carbohydrate metabolism in male Wistar rats were investigated. Daily intraperitoneal administrations of 1 mg/kg body weight of aluminium or aluminiumcitrate (1: 1) for 50 days led to the elevation of serum insulin by 24 or 40 percent respectively, with the concomitant decrease in serum glucose concentrations ...

background: ectopic pregnancy is one of the pathologic entities that it destroys the fallopian tube and impairs the future pregnancy. there are different medical and surgical therapies in order the treatment and reserve of fertility. the aim of this report is discuss a case of successful intrauterine after management of ectopic pregnancy with local injection of kcl in an infertile pcod patient....

introduction: the incidence of chromosomal abnormalities was investigated in untransfered embryos reuslted from in vitro fertilization (ivf) or intracytoplasmic sperm injection (icsi) procedures. materials and methods: a total of 238 embryos of varying morphology between the pronucleated stage and 8-cells were analysed. the cytogenetic method of dyban was used for chromosome preparation. embryo...

prangos ferulacea is a plant found in the mediterranean and middle-east regions used as carminative, anti-flatulent, emollient and antibacterial herb. it is believed that the coumarins are responsible for some of known effects of  prangos . in this research the relaxant effects of p. ferulacea coumrin rich extract as well as osthole as its main prenylated coumarins were investigated on rat ileu...

  Objective(s): In nuclear medicine studies, gallium-68 (68Ga) citrate has been recently known as a suitable infection agent in positron emission tomography (PET). In this study, by applying an in-house produced 68Ge/68Ga generator, a simple technique for the synthesis and quality control of 68Ga-citrate was introduced; followed by preliminary animal studies. Methods: 68GaCl3 eluted from the ge...

objective(s) sildenafil citrate is a new drug and has special properties that bring about nitric oxide effects on vascular smooth muscle. the aim of this study was to assess the effects of ovarian stimulation and sildenafil citrate injection on pinopode expression in mice. materials and methods thirty adult female mice were randomly divided into three groups: control, hyperstimulated and hypers...

seeds of moringa peregrina (forssk.) fiori. (moringaceae) is widely used in south east of iran for gastrointestinal disorders. however, so far there is no pharmacological evidence for antispasmodic activity of this plant extract. therefore, the aim of this research was to investigate antispasmodic activity of m. peregrina on rat isolated ileum contraction. hydroalcoholic extract was obtained by...
