Bioevaluation of agro-waste for postprandial glucose and insulin concentration in blood.

OBJECTIVE: To evaluate the effect of cookies supplemented with apple pomace and mango-peel powder on postprandial glucose and insulin concentration. METHODS: The experimental study was conducted from February to August, 2018, at the Nutrition Counselling Centre, Government College Women University, Faisalabad, Pakistan. Different cookies with apple pomace and mango-peel powder were prepared and the most nutritive acceptable cookies were used to determine their postprandial effect on glucose and insulin concentrations against the control cookies made with white flour only in female subjects. Adult women were selected through advertisement with normal body mass index. Data was analysed using SPSS 17. RESULTS: All the 30 subjects received enriched and control cookies at different time slots during the study. The overall mean age of the sample was 25±10 years and each subject had body mass index <25kg/m2. Overall blood glucose and insulin concentrations were significantly lower with treatment cookies , compared to the control cookies (p<0.05). CONCLUSIONS: It was evident that fruit processing waste can be used as a nutraceutical agent in diet-based modules.

Effect of Organophasphate poisoning among patients reporting at a tertiary healthcare facility of Sindh Pakistan.

OBJECTIVE: To determine the effect of organophosphate poisoning (OPP) among patients at tertiary healthcare, Pakistan. METHODS: This cohort study was conducted over a six-year period (January 2011 to December 2016) of OPP patients admitted to the intensive care unit of Peoples University of Medical & Health Sciences for Women SBA, Hospital Pakistan and their outcome was determined. RESULTS: Total mortality was 17.39% (84 deaths in 483 patients, excluding those referred to Karachi). Out of these 84 deaths, 65 patients (13.46%) expired due to cardiorespiratory failure, 17 deaths (3.52%) followed due to complication of mechanical ventilation & ICU acquired infection and two deaths (0.41%) occurred due to renal failure. The major cause of poisoning was deliberate self-harm /suicidal intention (93.02%), with gender distribution of female (57.07%) and male (35.95%), followed by unintentional/accidental exposure (6.98%) in males. The intensive supportive treatment, precise and appropriate respiratory care, and adequate amount of atropine and pralidoxime doses are keys to reducing the OPP patient's mortality. CONCLUSION: Organophosphate poisoning (OPP) intoxication is common in female gender. The easy availability of these harmful compounds has resulted in increased mortality either by accidental exposure or most often by the deliberate suicidal attempt.

Screening of indigenously isolated fungi for lovastatin production and its in vivo evaluation.

Seven indigenously isolated fungal strains (Aspergillus niger, Aspergillus flavus, Aspergillus terreus, Penicillium citrinum, Penicillium notatum, Pleurotus ostreatus and Trichoderma viradae) were tested for their potential to produce cholesterol lowering drug lovastatin by using different agro-industrial wastes (Corn cobs, corn stover, banana stalk, wheat straw, wheat bran, bagasse) in submerged as well as solid state fermentation. Aspergillus terreus showed maximum production of 18.74 mg/100 mL by wheat bran in solid state fermentation. The fermentation parameters (pH, temperature, Inoculum size, moisture contents and fermentation time) were also optimized for optimum production of lovastatin. It was found that Aspergillus terreus could produce 27.14 mg/100 mL lovastatin under optimum condition of pH (6), temperature (30°C), Inoculum size (2 mL), moisture contents (60%) and fermentation time (120 hrs) in solid state fermentation. The optimized lovastatin was extracted from fermented broth and orally administered to rats. The hypocholesterolemic effect of fermented lovastatin was evaluated on serum ALT, AST, HDL-C, LDL-C, TG and TC level of rats. It was concluded from the study, fermented lovastatin effectively lower the cholesterol level of rats.

Salinity and drought induced antioxidant responses in different cultivars of safflower (Carthamus tinctorius L.).

Six cultivars of safflower which were (PI-387820, PI-251978, PI-170274, PI-387821, PI-386174 and Thori-78) grown in net house of NIAB under salinity (10 ds m⁻¹) and drought (60% field capacity) conditions and compared to their oxidative damage and antioxidative responses. Plant samples (leaves) were collected for the determination of malonidialdehyde (MDA), antioxidative enzymes (catalase, ascorbate peroxidase, glutathione reductase, and peroxidase), proline, and photosynthetic pigments. Salinity and drought decreased the chlorophyll a and b contents but a decrease in chlorophyll a and b was less in safflower variety (THORI-78) which could be a useful marker for selecting a stress tolerant variety. Both stresses considerable increases the accumulation of proline in PI-251978, PI-170274, PI-387821, PI-386174 and THORI-78 varieties of safflower whereas the proline accumulation did not appear to be an essential part of the protection mechanism against salinity and drought in variety PI-387820. Enzyme activity measurements revealed that THORI-78 can tolerate salinity and drought stress well by increasing the activity of catalase and APX enzymes whereas variety PI- 386174 showed increased activity of glutathione reductase enzyme under salinity and drought and appear to be very crucial antioxidative defenses during intense stress conditions. The results indicate that the photosynthetic pigments, proline and activities of the enzymes are important mechanism for the stress tolerance in safflower plant and can be considered as genetic improvement for the plant in salinity and drought soil conditions.
