Antidiabetic, Antihyperlipidemic and Antioxidant Activities of Buchanania lanzan Spreng Methanol Leaf Extract in Streptozotocin-Induced Types I and II Diabetic Rats

Purpose: To evaluate the antidiabetic, antihyperlipidemic and antioxidant activities of Buchanania lanzan.Methods: Wistar rats were divided into nine groups of six animals each, and 40 mg/kg of streptozotocin or streptozotocin + nicotinamide was administered intraperitonially to induce types I and II diabetes. Those with blood glucose levels > 190 ± 8 mg/dl were administered the methanol leaf extract of Buchanania lanzan (MEBL, 100 or 200 mg/kg, p.o.) or positive control for 21 days. Blood glucose, lipid profile, antioxidant enzymes and oxidative stress markers were evaluated.Results: Following induction, blood glucose level rose to 327.7 ± 47.4 mg/dl, compared to the normal value of 910 ± 3.2 mg/dl. Administration of MEBL (100 or 200 mg/kg) significantly (p < 0.05) decreased blood glucose level, serum lipid profile, and significantly (p < 0.05) increased antioxidant activity as evidenced by increase in super oxide dismutase (SOD), catalas, glutathione (GSH), and decrease in the activity of lipid peroxidation (LPO).Conclusion: MEBL exhibits antidiabetic, antihyperlipidemic and antioxidant activities in diabetic rat and needs to be further investigated for the treatment of both types I and II diabetes mellitus.Keywords: Antidiabetic, Antihyperlipidemic, Antioxidant, Buchanania lanzan

Method development and validation of a reversed phase HPLC method for determination of Anastrazole and Temozolomide in pharmaceutical dosage form

A new simple assay method has been developed and validated for the determination of Anastrazole and Temozolomide using reverse-phase high-performance liquid chromatography in their pharmaceutical dosage form. The chromatographic separation was performed on an Inertsil ODS (4.6 x 150mm, 5m) using mobile phase phosphate buffer pH 3.0 and methanol of 30:70% v/v at a flow rate of 0.8mL/min. Analytes were detected at 260nm. The method was found to be linear in the concentration range of 1-5μg/mL for both medicaments with the coefficient value (R2) of >0.999. The accuracy was measured via recovery studies and found to be acceptable and the percentage recoveries were found in the range of 98.81-100.720 and 99.290-100.700%. The proposed method was successfully validated and applied for the quantitative estimation of these drugs in both bulk and tablet dosage forms. © 2020 Author(s)

Massive spontaneous corpus callosal hemorrhage with intraventricular extension

Spontaneous hemorrhage into the corpus callosum with intraventricular extension is uncommon. In the present article we describe a case 60 year female who had massive hemorrhage along the corpus callosum involving genu, body of corpus callosum and extending on ventral as well as dorsal aspect of the corpus callosum with intraventricular extension and areas of hypodensities in the body of the corpus callosum and adjacent cerebral cortex. In this case the subarachnoid and corpus callosal hemorrhage probably resulted from the ruptured aneurysms of the anterior cerebral artery

Design and Synthesis of Metal Complexes of (2 E

The photocatalytic degradation has been considered to be an efficient process for the degradation of organic pollutants, which are present in the effluents released by industries. The photocatalytic bleaching of cationic dye methylene blue was carried out spectrometrically on irradiation of UV light using Cu(II), Ni(II), and Co(II) complexes of (2E)-2-[(2E)-3-phenylprop-2-en-1-ylidene]hydrazinecarbothioamide (HL). The effects of pH and metal ion were studied on the efficiency of the reaction. Cu(II) complex shows better catalytic activity and the highest percentage degradation (~88.8%) of methylene blue was observed at pH 12. A tentative mechanism has also been proposed for the photocatalytic degradation of methylene blue

RP-HPLC Method for the Simultaneous Analysis of Ambroxol Hydrochloride and Nitazoxanide in API and Tablet Dosage Form

Present work is aimed to develop a new simple, fat, rapid, accurate, efficient, and reproducible RP-HPLC method for the simultaneous analysis of Ambroxol Hydrochloride and Nitazoxanide in API& tablet dosage form. The chromatographic separation was performed using phenomenex C18 Column having dimensions of 4.6x250mm having particle size of 5 μm, with mobile phase consisting of Buffer PH-3.5 and Acetonitrile (40:60% v/v), flow rate was adjusted to 1.0ml/min and detection wavelength at 235 nm. The proposed method has been validated for linearity, range, precision, accuracy and robustness were within the acceptance limit according to the ICH Q2B guidelines. The retention times of Ambroxol Hydrochloride and Nitazoxanide were 2.985 mins and 5.581 mins respectively. The linearity was performed in the concentration in the range of 7.5 μg/ml to 45 μg/ml and 25 μg/ml to 150 μg/ml and with a correlation coefficient of 0.999 and 0.999 respectively. % RSD for system precision was found to be 0.212 and 0.160% RSD for repeatability 0.2 and 0.12, % RSD for intermediate precision was 0.06 and 0.06 respectively. The % percentage purity of Ambroxol Hydrochloride and Nitazoxanide was found to be 99.93% and 99.35% respectively. The method was found to be robust even by change in the mobile phase ±5% in less flow condition. © 2022 Author(s)

A new validated RP-HPLC method for the determination of Tinidazole and Roxithromycin in its bulk and pharmaceutical dosage forms

To develop and validate a novel reverse-phase high-performance liquid chromatography determination of Tinidazole and Roxithromycin in its Bulk and Pharmaceutical Dosage Forms. Examination of simultaneous determination is centered around the advancement of novel RP-HPLC systematic technique for the assurance of medication substance in strong oral dose shapes and their approval. The optimized chromatographic condition was established for the estimation of Tinidazole and Roxithromycin by using Agilent C18 (4.6 X 250mm, 5μm) column, sodium acetate buffer (pH 3) and Methanol (30:70% v/v) as mobile phase at a flow rate of 1.0ml/min sustain an ambient temperature. The total analysis time was 10 minutes and the retention of Tinidazole and Roxithromycin was found to be 2.352 and 5.941min with an injection volume of 20μl. The system suitability parameters proved for optimized chromatographic conditions for Tinidazole and Roxithromycin were within limits. The developed method was showing good resolution and separation factors. © 2020 Author(s)

Prospects of new chickpea varieties in Andhra Pradesh

Andhra Pradesh is an important chickpea growing state in southern India, with spectacular increase in chickpea area from 120,000 ha in 1997/98 to 638,000 ha in 2007/08. The chickpea revolution in Andhra Pradesh has improved the prospects of many resource-poor, small land holding and rainfed farmers of Andhra Pradesh. However, the growing season of chickpea in Andhra Pradesh is warm and short (90-110 days), and drought is the foremost factor responsible for significant yield losses. Rainfall in major chickpea-growing regions is quite uncertain and erratic, resulting in poor yields. The Regional Agricultural Research Station of Acharya N G Ranga Agricultural University, Nandyal, Andhra Pradesh, India is the lead centre responsible for location-specific research in chickpea in Andhra Pradesh. With support from ICRISAT and ICAR, the centre has initiated crop improvement programmes during 2004 and has released four promising chickpea varieties for commercial cultivation. Three desi varieties viz., Nandyal Sanaga 1(NBeG 3), Dheera (NBeG 47), and Nandyal Gram 49 (NBeG 49) released for Andhra Pradesh and one large-seeded kabuli Nandyal Gram 119 (NBeG 119) released for the southern zone comprising Andhra Pradesh, Karnataka and Tamil Nadu, are cutting across chickpea growing regions of Andhra Pradesh. Nandyal Sanaga 1, released in 2012, is a bold-seeded desi variety tolerant to drought and heat; Dheera released during 2015 is also a desi variety and the first of its kind in India, suitable for mechanical harvesting. Nandyal Gram 49 released during 2016 is a highyielding desi variety with attractive seeds; whereas Nandyal Gram 119 is early bold-seeded kabuli variety released during 2015. These varieties have clearly demonstrated their advantage (10%-15 % increase over popular varieties of the tract) in farmers’ holdings in large-scale demonstrations and are being preferred by farmers of not only Andhra Pradesh, but also Karnataka, Tamil Nadu, Odisha and Maharastra. Efforts are underway to promote large-scale adoption of these varieties to maximize long term productivity of chickpeas in rainfed vertisols
