OBJECTIVE
The aim of this study was to investigate blood folic acid and vitamin B12 levels in patients with ischemic and hemorrhagic stroke patients and correlate these levels with prognosis.
METHODS
Patients presenting within 3 hours of onset of ischemic or hemorrhagic strokes were approached for
Severe thrombocytopenia associated with acute folic acid deficiency in two inpatients is described. Both patients had severe hemorrhagic manifestations. A similar syndrome has previously been described in patients who have undergone extensive surgery or dialysis or both. The present cases show that
BACKGROUND
The association between the progestin-only pill used for treatment of menstrual disorders and central venous sinus thrombosis (CVST) has rarely been reported in the literature. This report describes a case of central venous sinus thrombosis following intake of norethindrone acetate for
OBJECTIVE

Four groups of pregnant rats were used to study the effects of dietary supplements of folic acid (FA) alone or a mixture of FA, vitamins (Vit), and amino acids (AA) on the teratogenic effects of phenytoin (PHT). Groups A, B, and C received intraperitoneal (i.p.) injections of high-dose (75
Pregnant rats were divided into four groups. The groups A, B and C were intraperitoneally injected with DPH during the 9 to 11 days of gestation in doses of 75 Mg/kg/day. The groups A and B were supplemented with a mixture of folic acid (FA) or with FA alone in the food fed during pregnancy. The
Endothelin (ET) signalling is essential for normal embryonic development. Disruption of this pathway leads to defects in the development of subsets of cranial and cephalic neural crest derivatives. Endothelin-converting enzyme 1 (ECE-1) is a ratelimiting step in the biosynthesis of ET-1. Recently,
