Lymphatic vascular endothelial hyaluronan receptor-1 immunoexpression in placenta of HIV infected pre-eclamptic women.

Introduction: Lymphangiogenesis is the formation of new vessels from pre-existing lymphatic vessels. Data on lymphangiogenesis in the placenta of HIV-infected pre-eclamptics are sparse and the findings are conflicting. The aim of this novel study was to evaluate LYVE-1 immunoexpression in the placenta of HIV infected normotensive versus pre-eclamptic women.

Morphological study of the effects of aqueous leaf extract of Xylopia aethiopica on the pancreas in diabetic rats.

To investigate the histological and immunohistochemical effects of aqueous leaf extract of Xylo- pia aethiopica on the pancreas in streptozotocin-induced diabetic rats, 30 adult Wistar rats were divided into three groups (n=10). Group A was the control (administered with equivalent vol- ume of citrate buffer), group B animals were made diabetic by a single intraperitoneal injection of streptozotocin dissolved in citrate buffer (65 mg/kg), group C animals were made diabetic as above and treated with 200mg/kg body weight of aqueous leave extract of Xylopia aethiop- ica for 25 days. Upon animal sacrifice, the pancreas were excised, fixed in 10% formol saline and processed for light microscopy and immunohistochemistry.

The microstructural effects of aqueous extract of Garcinia kola (Linn) on the hippocampus and cerebellum of malnourished mice.

Objective: To assess the neuroprotective effects of aqueous extract of Garcinia kola on neurotoxin administered malnourished mice adopting histological procedure.

Methods: The study was carried out using thirty-two adult malnourished mice which were randomly assigned into four groups (n=8): A, B, C and D. Group A served as control, while the other groups served as the experimental groups.

Histopathological studies of acute and chronic effects of Calliandra portoricensis leaf extract on the stomach and pancreas of adult Swiss albino mice.

Objective: To evaluate the consequence of oral administration of Calliandra portoricensis (C. portoricensis) leaf extract on the stomach and pancreas in Swiss albino mice.

Methods: Three groups of mice (B, C and D) were treated with 4 mg/kg of C.

Regenerative Potential of Aqueous Extract of Neem on the Stomach and Ileum Following Ethanol-induced Mucosa Lesion in Adult Wistar Rats.

Background: The aim of this study was to examine whether neem possesses regenerative potential on the stomach and ileum at 500 mg/kg dose given every 12 hours after mucosa lesion was brought by the administration of 1 ml of 50% ethanol for 21 consecutive days in adult Wistar rats.

Methods: Adult male Wistar rats used in the study were divided into 3 groups: group A received oral normal saline and served as control; group B received 1.0 ml of 50% ethanol orally every 12 hours; and group C received neem extract (500 mg/kg) orally 12 hours after ethanol (50%, 1.

Microanatomical effects of ethanolic extract of Cola nitida on the stomach mucosa of adult Wistar rats.

The study investigated the microanatomical effects of the extracts of Cola nitida on the stomach mucosa of adult male Wistar rats. Twenty adult male wistar rats were randomly divided into four equal groups of A, B, C and D (n = 5). Animals in experimental groups B, C and D were given 600 mg/kg body weight of crude extract of Cola nitida each by oral intubation for five, seven and nine consecutive days respectively, while group A (control) received equivalent volume of distilled water.
