Anticataract activity of rhamnocitrin isolated from Bauhinia variegata stem bark
Bodakhe, Surendra H.,Ram, Alpana,Verma, Suruchi,Pandey, Devi Prasad 경희한의학연구센터 2012 Oriental Pharmacy and Experimental Medicine Vol.12 No.3
A cataract is any clouding or opaque area in the eye's natural lens, which is normally crystal clear, is the leading cause of blindness worldwide. It accounts for approximately 42% of all blindness. Approximately 25% of the population over 65 and about 50% over 80 age has serious loss of vision because of cataract. Most cataracts progress and eventually hamper vision. Multiple mechanisms have been implicated in the development of cataract. But the exact pathogenesis which leads to opacification is not clearly known. Oxidative damage to the lens has been recognized as the initiating event in the pathogenesis of cataracts. In cataract, the oxidation-antioxidant equilibrium shift more towards oxidative stress. Accordingly, antioxidants could prove potential anticataract agents. Rhamnocitrin, a flavonoid, possess strong antioxidant effects; can be used effectively to manage the cataract. Therefore, anticataract activity of rhamnocitrin (10, 20, 40 and 80 ${\mu}g$), isolated from Bauhinia variegata (Leguminosae) stem bark, was studied in ovine and chick embryo lens model. It showed a significant protection against cloudiness in lenses induced by hydrogen peroxide and hydrocortisone in a dose dependent manner. The findings suggest that rhamnocitrin possess significant anticataract activity and act most likely due to its antioxidant property.

Objectives: Several studies have revealed that systemic hypertension is strongly associated with cataractogenesis. However, the pathophysiology and treatment is often unclear. In this study, we evaluated the anti-cataractogenic effect of cinnamaldehyde (CA), a natural organic compound, in rats with fructose-induced hypertension. Methods: The rats were divided into six groups. For six weeks, the normal group received a suspension of 0.5% carboxy methyl cellulose (10 mL/kg/day, p.o.) while five other groups received a 10% (w/v) fructose solution in their drinking water to induce hypertension. By the end of the third week hypertension had been induced in all the animals receiving fructose. From the beginning of the fourth week to the end of the sixth week, one of those five groups (control) continued to receive only 10% (w/v) fructose solution, one group (standard) received ramipril (1 mg/kg/day, p.o.) plus 10% (w/v) fructose solution, and three groups (experimental) received CA at doses of 20, 30, and 40 mg/kg/day p.o., plus 10% (w/v) fructose solution. Blood pressure was measured weekly using a non-invasive blood pressure apparatus. After six weeks, the animals were sacrificed, and the anti-cataractogenic effects on the eye lenses were evaluated. Results: Administration of fructose elevated both the systolic and the diastolic blood pressures, which were significantly reduced by CA at all dose levels. In the control group, a significant increase in the malonaldehyde (MDA) level and decreases in the total protein, $Ca^{2+}$adenosine triphosphate (ATP)ase activity, glutathione peroxidase, catalase, superoxide dismutase and glutathione levels, as compared to the normal group, were observed. Administration of CA at all doses significantly restored the enzymatic, non-enzymatic, antioxidants, total protein, and $Ca^{2+}$ATPase levels, but decreased the MDA level, as compared to the control group. Conclusion: The present study revealed that CA modulated the antioxidant parameters of the serum and lens homogenates in hypertension-induced cataractogenic animals.

Assessment of the Antiulcer Potential of Moringa oleifera Root-Bark Extract in Rats
Manoj Kumar Choudhary,Surendra H. Bodakhe,Sanjay Kumar Gupta 사단법인약침학회 2013 Journal of Acupuncture & Meridian Studies Vol.6 No.4
In the present study, an ethanolic root-bark extract of Moringa oleifera (MO) was examined for its antiulcer potential in albino Wistar rats using two experimental models: ethanol-induced and pylorus ligation-induced gastric ulceration. The extract was orally administered at three different doses (150, 350, and 500 mg/kg) for 15 consecutive days. The antiulcer effects in rats treated with different doses of the extract and omeprazole (30 mg/kg, p.o.) were determined and compared statistically with the antiulcer effects in the control rats treated with saline (NaCl, 0.9%). The MO at doses of 350 and 500 mg/kg decreased the ulcer index significantly as compared to the control group (p < 0.01). The percentage protections against gastric ulcers were 82.58%, 85.13%, and 86.15% for MO doses of 150, 350, and 500 mg/kg, respectively, in the pylorus-ligated ulcer model and 55.75%, 59.33%, and 78.51%, respectively, in the ethanol-induced ulcer model. The MO significantly reduced the free acidity, total acidity, and ulcer index (p < 0.01) and increased the pH of gastric content compared with the control group. This study suggests that MO possesses valuable antiulcer, antisecretory, and cytoprotective activity. Thus, an ethanolic root-bark extract of Moringa oleifera can be used as source for an antiulcer drug.
