Abstract
Amylase biosynthesis was illustrated under stress circumstances of high temperature and high salinity in aerobically cultivated culture of a newly isolated moderately thermophilic bacterium of spore-forming
Bacillus sp. NRC12017 in medium containing starch, peptone and yeast extract. Maximum yield (18.41 U/ml) was took place at pH 6.5 with 200 µl inoculum size at 45°C and an incubation time of 3 days. The ideal volume of the fermentation broth was found to be 15 ml in 100 ml Erlenmeyer flask, supplementation of starch at 2.5% and peptone plus yeast extract at 0.7% brought about the greatest production of α-amylase. Two fractions of α-amylase activities, designated FIII and FIV, were refined from culture filtrate utilizing ammonium sulfate (60 and 80%) and showed the main band at 30 KDa. Both fractions had the highest activity at 250 µl starch in a reaction mixture and pH 6.0-7.0. FIII and FIV showed that a temperature of 50 and 55°C and a reaction time of 20 and 30 min were the best available conditions for their activities, respectively, both fractions were stable up to 65°C and the activity was decreased drastically to 3.22 and 3.26 % when heated at 70°C. Concerning pH stability, a broad range of pH stability (5.0-11.0) was obtained by FIII and FIV.

Abstract
Water from holy zamzam is consumed by many Muslims in the world due to its beneficial role for the health of human beings. Therefore the present study was designed to evaluate the effect of zamzam water in diabetes mellitus, nephrotoxicity and hepatotoxicity in rats as well as to determine the chemical analysis of this water. Fifty six male albino rats weighting (150±5gm) were divided into four main groups and each group was divided into two subgroups a and b, one administered tap water (Tw) and the other subgroup administered zamzam water (zw). The 1
st main group was normal rat (-ve control), the 2
nd group was diabetic (induced by alloxan 150 mg/kg b.w.), the 3
rd was nephrotoxic (induced by gentamicin 100 mg/kg b.w.) and the 4
th group was hepatotoxic by carbon tetrachloride (2ml/ kg b.w.). The experiment lasted after four weeks. Zamzam water significantly decreased serum glucose, total lipids, total cholesterol, triglycerides, LDL-cholesterol and elevated HDL- cholesterol. Moreover the liver and kidney markers were also improved in the groups that treated with zamzam water relative to its control taking tap water. Zamzam water has a protective role against hazardous effects of diabetes mellitus, nephrotoxicity and hepatotoxicity in rats.

Abstract
Objectives are to determine antifungal activity of Ivermectin and Calvatia craniiformis as a novel alternative therapy for aspergillus niger associated acute otitis media (AOM) among rural children of Diyala province; correlation of sociodemographic factors with frequency of infection. Ear swabs taken from 58 infected children and cultured on Sabouraud dextrose agar for 7-14 days .Macroscopic and microscopic criteria used for diagnosis of A.niger .High isolation rate for A.niger (27.59%) among children of (4-6) years with significant difference between age groups ( p value 0.039); genders ( p value 0.004);house status(p value=0.018);family size (p value =0.00006334) and month of infection (p value=0.000). A.niger infection negatively correlated with patients age (p value =0.039), family economy and house status (p value =0.000),family size (p value =0.000). Alcohol extract of
C.craniiformis (100mg, 200mg, 400mg, 500mg, 600mg, 800mg and 1000 mg) and ivermectin (0.5%,1 % and 2%) restricted the growth of A. niger after 3 days .Significance difference reported between all concentrations except 100 mg and 200 mg ; 600 mg and 800 mg. Significance difference in inhibitory activity between concentration 1% and 2%,0.5% and 2% of Ivermectin respectively. Conclusions: A.niger infections positively correlated with family size and inversely with age and family economy. The growth of
A niger significantly restricted by alcohol extract of C.craniiformis and Ivermectin in concentration dependent manner. The powerful concentration was 1000mg, for
C.craniiformis and 2% for Ivermectin. Thus, C.craniiformis and Ivermectin consider a novel antifungal agents that can be used in clinical practice for treatment of
A.niger associated otitis media that represents a clinical problem in children and need serious attention from clinicians.

Abstract
The toxicity of various forms of mercury to the living organisms is well documented. Mammalian kidney is the main site of decomposition of inorganic mercury as well as the target organ for its toxicity in majority of the animals including human beings. Present study has been aimed to investigate the role of
Tagetes erecta (family-Astereacea) as a possible modifier of mercury induced renal damages. Experimentation was conducted on one hundred female albino rats, divided into five equal groups, each group again sub-divided into four sub-groups having five rats each: Control group- Orally administrated distilled water only.
T. erecta flower extract treated group-10mg/kg b. wt./day for 1, 7, 14, 21 days was administrated orally. Mercuric chloride treatment groups-A dose of 0.926 mg/kg b.wt. for 01 day, 0.132 mg/kg b.wt. for 7 days, 0.066 mg/kg b.wt. for 14 days and 0.044 for 21 days was administrated through oral route.Oral administration of
T. erecta flower extract followed by mercuric chloride treatment for 1, 7, 14 and 21 days.Oral administration of Mercuric chloride followed by
T. erecta flower extract administration for 1, 7, 14 and 21 days.These animals were then sacrificed after 1, 7, 14 and 21 days treatment respectively. Controls were also run respectively. Mercuric chloride intoxication resulted in pathological alterations in the kidney of albino rats, such as degradation of glomerulus, proximal and distal tubules. Combined pre and post treatment of
T. erecta with mercuric chloride has been found to reduce the pathological alterations in the kidney. Thus, the results from the present study suggest that
T. erecta can modify the renal damages against mercuric chloride induced toxicity.

Abstract
Parkinson’s disease (PD) is an age related neurodegenerative disorder characterized by the dopaminergic neurons loss in the midbrain. Even though there are some drugs in the market to ease parkinsonian symptoms, an accurate drug to prevent or cure the disease is still unknown. This study is an attempt to estimate
in silico; a bioactive plant fucocoumarin Imperatorin; for its ability as an anti-PD drug, using Autodock 4.2, Pre-ADMET and molinspiration tools against the antioxidants involved in neuropathology of PD, keeping amantadine as a positive control. The molecules selected for the study are Cyclo- Oxygenase 1 (COX-1), Homo-Oxygenase-1(HO-1), NRF2-Keap1, Lipo-Oxygenase 1(LOX-1), Phospholipase A2 (pA2), DJ-1 and superoxide dismutase (SOD). The reliability of the 3 Dimensional (3-D) structures generated were confirmed using WHATIF Server. The study predicted Imperatorin as a potent anti-PD drug, being good inhibitors of COX-1, HO-1 and LOX-1, having less human toxicity and better ability to cross Blood Brain-Barrier (BBB).

Abstract
Nanoparticles are gaining interest in biomedical applications due to its importance such as anti-bacterial, anti-fungal and anti-cancer agents. Conventional methods for the synthesis of metal nanoparticles involves toxic reagents which produce harmful by-products and are hazardous to the environment. To overcome these limitations, green synthesis of nanoparticles was established. Eco-friendly methods using plant extracts are gaining popularity due to the abundance of raw materials and the production of non-toxic by-products threatening to the environment. Moreover, the nanoparticles synthesized from the plant extract are cost-effective. In addition, nanoparticles produced by green synthesis methods produces synergetic effect where both the nanoparticles as well as the natural bioactive constituents of the plant influence the biocidal properties. Different methods namely heating in water bath, microwave oven and exposure to bright sunlight were adopted for the synthesis of silver nanoparticles. Plant extract based synthesis of silver nanoparticles was eco-friendly and shows an alternative promise in bio-medical applications and it undertakes the negative effects of synthetic drugs.
