Aqueous extract of Peristrophe bivalvis (L.) Merr. leaf reversed the detrimental effects of nitric oxide synthase inhibitor on blood lipid profile and glucose level.

There is evidence that nitric oxide (NO) modulates the metabolism of glucose and lipid, and some antihypertensive medications have been shown to affect glucose and lipid metabolism. Peristrophe bivalvis is a medicinal plant that has been shown to have antihypertensive properties. The study investigated the effect of aqueous extract of Peristrophe bivalvis leaf (APB) on fasting blood glucose level (FBG) and lipid profile in rats pretreated with nitro-L-arginine methyl ester (L-NAME).

The Antihypertensive Potential of Aqueous extract of (L.) Merr. is Up-regulation of Cyclic Guanosine Monophosphate and Down-regulation of the Renin-angiotensin System.

Background: Hypertension is a major risk factor for cardiovascular diseases. (PB) is used for the treatment of hypertension, painful sprains, skin diseases, tuberculosis, acute bronchitis, anti-inflammatory conditions, hepatitis, and diabetes. Its antihypertensive potential has been investigated and documented.

Vincristine attenuates isoprenaline-induced cardiac hypertrophy in male Wistar rats via suppression of ROS/NO/NF-қB signalling pathways.

Vincristine (VCR), a vinca alkaloid with anti-tumor and anti-oxidant properties, is acclaimed to possess cardioprotective action. However, the molecular mechanism underlying this protective effect remains unknown. This study investigated the effects of VCR on isoprenaline (ISO), a beta-adrenergic receptor agonist, induced cardiac hypertrophy in male Wistar rats.

Effect of silymarin on blood coagulation profile and osmotic fragility in carbon tetrachloride induced hepatotoxicity in male Wistar rats.

Reports about the impact of Carbon tetrachloride (CCl) hepatotoxicity on coagulation profile have been inconsistent. Multiple investigators have however demonstrated the effectiveness of silymarin in the resolution of anomalies induced by CCl, although the effect of silymarin on the impact of CCl hepatotoxicity, especially coagulation profile and osmotic fragility have not been investigated. The liver, the primary site for the secretion of coagulation proteins, can become impaired in CCl hepatotoxicity, and silymarin reportedly increases hepatic protein synthesis as part of its hepatoprotective mechanism.
