Study of vitamin D level in patients with different etiologies of chronic liver disease and its correlation with Child Pugh class in a tertiary care centre in North India

Background: Skeletal manifestation in liver diseases represents the minimally scrutinized part of the disease spectrum. Vitamin D has a central role in developing hepatic deficiency of osteodystrophy in patients with chronic liver disease. This study aimed to investigate vitamin D levels and their and their relationship with disease advancement in these patients according to child Pugh-score. Aims and Objectives were study of vitamin D level in patients with different aetiology of chronic liver disease and its correlation with child Pugh score. Methods: This was a cross sectional study conducted over 200 patients after applying inclusion and exclusion criteria in patients with different etiology of chronic liver disease. Results: In our study total (N=200), 152 patients of alcoholic liver disease 41 patients having deficient vitamin D, 79 having insufficient vitamin D level and 32 patients having normal vitamin D level. Patients of chronic liver disease also have negative correlation on vitamin D level with Child Pugh score. In our study it was found that patients having higher Child Pugh score there is more chance of having vitamin D deficiency and insufficiency than the patient’s low Child Pugh score. Conclusions: The prevalence of vitamin d deficiency in patients with CLD was found to be having a significant correlation with increasing CTP score with p value <0.001

Phytochemical and In Vitro Cytotoxic Screening of Chloroform Extract of <i>Ehretia microphylla</i> Lamk

Ehretia microphylla of the Boraginaceae family has been extensively used as a folklore remedy for the treatment of a wide range of ailments such as cough, cancer, allergies, and gastrointestinal and venereal disorders. Extensive literature review reports have revealed these findings due to the presence of numerous phytomolecules. To validate traditional claims for cytotoxic activity of E. microphylla, the present study was undertaken. Dried leaves of the plant were powdered and defatted with petroleum ether followed by hot continuous extraction with chloroform. The chloroform extract was subjected to in vitro cytotoxic screening against a panel of human cancer cell lines such as HCT-116 (colon), MCF-7 (breast), PC-3 (prostate), A-549 (lung), HL-60 (leukemia) and MiaPaCa-2 (pancreatic) at 50 µM using SRB assay. The extract exhibited noteworthy cytotoxicity activity against breast and lung cancer. It exhibited 85.55% and 77.93% inhibition against MCF-7 and A-549 cancer cell lines, respectively. The mechanism behind cell death was determined using the DAPI staining method, which induces alteration in nuclear morphology in MCF-7 cell lines evidenced through DAPI staining. Phytochemical screening of E. microphylla extract showed the presence of saponins, steroids, lipids, tannins and triterpenoids. The chemoprofile of the chloroform extract of E. microphylla leaves was established using an n-hexane:ethyl acetate solvent system in a ratio of 6:4. The developed chromatogram showed five spots both in visible and UV light at 254 nm. The information provided in the present study will enable further studies on the isolation and characterization of bioactive compounds/fractions by following bioactivity-guided fractionation, and thus, the plant has the potential to reduce proliferation and may induce cell death via apoptosis in breast cancer cells

Remote ischaemic preconditioning and prevention of cerebral injury

247-252Bilateral carotid artery occlusion of 10 min followed by reperfusion for 24 hr was employed in present study to produce ischaemia and reperfusion induced cerebral injury in mice. Cerebral infarct size was measured using triphenyltetrazolium chloride staining. Short-term memory was evaluated using elevated plus maze. Inclined beam walking test was employed to assess motor incoordination. Bilateral carotid artery occlusion followed by reperfusion produced cerebral infarction and impaired short-term memory, motor co-ordination and lateral push response. A preceding episode of mesenteric artery occlusion for 15 min and reperfusion of 15 min (remote mesenteric ischaemic preconditioning) prevented markedly ischaemia-reperfusion-induced cerebral injury measured in terms of infarct size, loss of short-term memory, motor coordination and lateral push response. Glibenclamide (5 mg/kg, iv) a KATP channel blocker and caffeine (7 mg/kg, iv) an adenosine receptor blocker attenuated the neuroprotective effect of remote mesenteric ischaemic preconditioning. It may be concluded that neuroprotective effect of remote mesenteric ischaemic preconditioning may be due to activation of adenosine receptors and consequent activation of KATP channels in mice
