RESUMEN

Present study was conducted in 120 day-old unsexed broiler chicks. They were randomly distributed into 4 dietary treatments (T1, T2, T3 and T4) supplemented with leaf meal mixture (LMM) of Eugenia jambolana and Psidium guajava@ 0, 2.5, 5.0 and 7.5 % of diet, respectively of 30 birds per treatment, each having 3 replicates (10 chicks per replicate) in a complete randomized block design (CRD). Significantly (P<0.05) higher mean body weight was observed in T1 as compared to T2, T3 and T4 groups. Carcass yields viz. live weight, de-feathered weight, slaughtered weight and eviscerated weights (in gram and % LWt.) were statistically non significant (P>0.05) with and without LMM supplemented diets. However, weights of spleen and liver were significantly (P<0.000, P<0.026) higher in LMM supplemented groups as compared to un-supplemented control (T1). Dietary supplementation significantly reduced abdominal fat content in T4 compared to T1, whereas, T2 and T3 have an intermediate values between T1 and T4 and increased the net profit, it ranged from ` 30.41 to 34.24 per bird

RESUMEN

Present study was undertaken in 120 day-old broiler chicks, randomly distributed into 4 dietary treatments (T1, T2, T3 and T4 supplemented with leaf meal mixture (LMM) of Eugenia jambolana and Psidium guajava @ 0, 2.5, 5.0 and 7.5 % of diet, respectively) each having 3 replicates (10 chicks/ replicate) in a complete randomized block design (CRD). Experimental chicks were fed basal diets (starter and finisher) supplemented with graded levels of LMM. Feed intake, body weight gain and feed conversion ratio (FCR) were recorded at weekly intervals. Two birds from each replicate were slaughtered at the end of feeding trial (42 days). Blood samples were collected and serum separated for biochemical profiles. For histopathological examination, representative tissue samples were collected in 10% neutral buffer formalin and then processed for paraffin embedding employing alcohol as dehydrating agent and xylene as clearing agent. Sections were cut at 4-5µm thickness and stained by routine haematoxylin and eosin method. On histopathological examination of liver, kidney, heart and intestine of T1 and T2 groups showed normal integrity, mild to moderate histopathological changes in T3 group, while, T4 showed drastic histopathological changes. It was concluded that E. jambolana and P. guajava LMM supplementation (2.5% or even 5%) maintained birds performance, minor histopathological changes and producing healthy low cholesterol broiler meat. The LMM incorporation (2.5%) in the diet of broiler chicks may be recommended as socioeconomic, alternative functional feed resource

RESUMEN

Background & objectives: Polycystic ovary syndrome (PCOS) is an endocrinopathy warranting lifelong individualized management by lifestyle and pharmacological agents mainly oral contraceptive pills (OCPs). This study was aimed to report the impact of six-month OCP use on plasminogen activator inhibitor-1 (PAI-1) and factor VIII (FVIII) in women with PCOS. Methods: PCOS women diagnosed on the basis of Rotterdam 2003 criteria, either treated with OCPs (ethinyl estradiol-0.03 mg, levonorgestrel-0.15 mg) for a period of six months (n=40) or drug-naïve (n=42), were enrolled in this study. Blood was drawn to estimate glucose, insulin levels and lipid profile. Chemiluminescence immunoassays were used to measure hormones (LH, FSH, PRL, T4). Plasma levels of PAI-I and FVIII were measured by commercially available kits. Results: Menstrual regularity, Ferriman-Gallwey score and serum total testosterone significantly improved in the OCP group compared to drug-naïve group (P<0.01). No significant difference was observed in PAI-1 levels of the two groups; however, significant decrease in FVIII levels was observed in OCP group as compared to drug-naïve group. PAI-1 levels of OCP group correlated positively with blood glucose two hours, triglycerides and insulin two hours, while FVIII levels of OCP group correlated negatively with fasting insulin and homoeostatic model assessment-insulin resistance. Interpretation & conclusions: OCPs use has differential effect on pro-coagulant markers among women with PCOS. Well-designed, long-term, prospective, large-scale studies are prerequisite to elucidate the efficacy and safety of OCP in the treatment of PCOS.

RESUMEN

Oxidative stress is the root cause of many diseases, affecting the humans by deranging the balance between the oxidants and antioxidants. Pathologies, such as Alzheimer’s, Parkinson’s, diabetes and cancer have been well associated with the production of free radicals during various metabolic processes. Many medicinal plants are used to treat such kind of diseases since ancient times. Here, we evaluated the medicinal herb Rheum spiciformis Royle (RS), used commonly in folklore to treat many aliments for its potential against oxidative stress. Five different extracts (aqueous, chloroform, ethyl acetate, methanol and PET ether) of RS were evaluated against oxidative stress generated in vitro. Phytochemical constituents were assessed followed by total phenolics, DPPH, reducing power, hydroxyl radical scavenging activity and in vitro calf thymus DNA damage. The highest phenolic content (TPC) of 1191.65 mg GAE/g was observed in RS-MeOH extract. DPPH radical scavenging activity was found to be highest in RS-MeOH (96.60%) with IC50 125.91 µg/mL. The reducing power of the extracts increased in a concentration dependent manner. Again superoxide radical scavenging activity of RS extracts with IC50 values 34.10 µg/mL (RS-MeOH) for methanol was highest. The H2O2 scavenging activity 84.76 µg/mL shown by RS-MeOH extract at 250 µg/mL of plant extracts was the maximum. RS-MeOH showed great effect to scavenge free radicals as such prevents Calf thymus DNA damage induced by Fenton reaction. These results clearly indicate that RS-MeOH and RS-EtA among the five extracts possesses the highest positive modulatory effect on free radical scavenging on wide variety of free radicals as such can be employed as potential antioxidant and anti-inflammatory agent against various oxidative stress related pathological conditions.
