The effect of aqueous leaf extract of Azadirachta indica (Neem) on reproduction was studied on male albino rats. The study was divided into three groups of six animals each. The first group (I) received distilled water serve as control. The second and third groups (II and III) of animals were administered the aqueous leaf extract daily at 250mg/kg body wt., and 350mg/kg body wt., respectively f...

Most of the commercial poultry growers use antibiotics for growth promotion and to many disadvantages like higher rearing cost, adverse side effects on health of birds, prolonged withdrawal period and residual effects. Some plants and their extracts improve feed intake and enzymatic activity of the birds. A few of these herbs have antimicrobial, Coccidiostatic or anthelmintic effects. A study w...

Azadirachta indica (neem) is the only source of azadirachtin, which is known for its insecticide activity. Melia azedarach is a related species of A. indica, widely distributed in the south of China. In this study, the leaf transcriptomes of these two Meliaceae plants were sequenced. More than 40 million clean reads were generated from each library. About 80 % of A. indica reads were mapped to ...

The effect of neem, Azadirachta indica A. Juss, on ultrastructural alteration of larvae and puparia of the blow fly, Chrysomya megacephala (Fabricius) (Diptera: Calliphoridae) and house fly, Musca domestica (Linnaeus) (Diptera: Muscidae), was investigated in the laboratory by using neem extract containing 0.24% azadirachtin A. Larvae of both species exposed to single dipping with the neem produ...

AIM To compare the antibacterial efficacy of Azadirachta indica (Neem), Commiphora myrrha (Myrrh), Glycyrrhiza glabra (Liquorice) with 2% Chlorhexidine (CHX) against E. faecalis by using Real Time PCR. MATERIALS AND METHODS A total of fifty teeth specimens (n=50) were inoculated with E. faecalis for 21 days. Specimens were divided into five groups (Group 1: Myrrh, Group 2: Neem, Group 3: Liqu...

Subcutaneous treatment of 50% EtOH extract of neem bark (Azadirachta indica A. juss) to male rats at the dose of 10 mg for 30 days caused arrest of spermatogenesis. The diameter of serminiferous tubule, Leydig cell nucleus and epithelial heights of epididymides were significantly reduced (p≤0.001). Sperm motility and density were significantly reduced. Reduced testicular and accessory organ pro...

Photolysis of Salannin (1), an important bioactive compound from Azadirachta indica A.Juss (Neem), affords ∆-isosalanninolide (2), a hitherto unknown compound, along with isosalanninolide (3) and salanninolide (4). A probable mechanism has been suggested. While the mechanism of formation of 2 involves both a [4+2] cycloaddition and a [1,3] sigmatropic shift in the furan and D-rings, respectivel...

Locusta migratoria, Azadirachta indica, Ecdysteroids, Azadirachtin, Ovary The sterilizing effect of azadirachtin, an insect growth regulator from the neem tree, Azadirachta indica A. Juss, was tested with mature females of Locusta migratoria. After a single injection of 10 |ig into females between 2 and 13 days after emergence, about 60% died during the following four days and all lost weight i...

Mammalian ovary is a dynamic organ that is responsible for the production of competent oocytes required for successful fertilization and early embryonic development [1,2]. The meiotic competency folliocular is achieved within the follicular environment during final stages of folliculogenesis [3-7]. The achievement of meiotic competency starts in diplotene arrested oocytes, possessing germinal v...

The in vitro fungitoxic activity of crude extracts of neem (Azadirachta indica) (A.) Juss) and pawpaw (Carica papaya) (L.) on Alternaria solani, isolated from rotting yam tubers whose pathogenicity has been proven and assessed. The organic solvent (methanol) extracts of leaves of neem and pawpaw at 20%, 40%, 60% and 80% concentrations were tested on potato dextrose agar (PDA) for activity again...
