Tissue culture of endangered Bael tree (Aegle marmelos ): A Review

Tissue culture is a proven means of producing millions of identical plants under a controlled and aseptic condition, independent of seasonal constraints. It not only provides economy of time and space but also gives greater output and allows further augmentation of elite disease free propagules.

Most of these crops have medicinal value and are suitable for growing under marginal situations. The commercial production of these crops is restricted due to the shortage of desirable planting material. Tissue culture can play an important role in rapidly increasing new cultivars of these fruit crops. This review paper outlines the work done on Aegle marmelos (Linn) family Rutaceae.

Aegle marmelos (Linn) family Rutaceae is highly reputed ayurvedic medicinal tree commonly known as the bale fruit tree, is medium sized tress growing throughout the deciduas forest of India of altitude 1200 meter. The collection and evaluation of over 1200 bael (Aegle marmelos Correa) trees in West Bengal was initiated in 1994. Six types have been identified as superior clones and are being conserved at the Faculty of Horticulture Research Station located at 23.5 North latitude and 89 East longitudes. Wide variability in yield (20–437 fruits/tree), fruit weight (130–1825 g), fruit shape, rind thickness, pulp colour, number of seeds, total soluble solids (23–42 °Brix), fruit acidity (0.23–0.44%) and ascorbic acid (22–30 mg/100 g) content of fruit were observed among the genotypes. The clones T1, T5, T8, T10, T15 and T16 were selected for cultivation. The method standardised could be used for large scale planting material production and conservation of this important endangered medicinal plant. The hardened plants are being evaluated under field condition. The micropropagated plants were tested for its genetic fidelity using 12 RAPD, 2 micro-satellite and 2 mini-satellite primers. Profile obtained by all the three single primer amplification reaction (SPAR) technique obtained from mother tree and micropropagated plants were found identical which suggests the genetic uniformity of micropropagated plants with that of mother tree.

Study on Effect of Solvents & Nonsolvents on Microspheres of Ciprofloxacin: Coacervation Phase Separation

The objective of the study was to determine the effect of solvents like acetone, dimethyldigol, 1, 4-dioxan and non-solvents like n-hexane and chloroform on microencapsulation of ciprofloxacin hydrochloride. The microspheres were prepared by following coacervation phase separation using various non- aqueous solvents and non-solvents like solvent evaporation and non-solvent addition method with rate retarding cellulose polymers. Microspheres were characterized for the particle size distribution, wall thickness by scanning electron microscopy (SEM), angle of repose, bulk density, percent drug content, entrapment efficiency and in vitro dissolution studies. Drug excipient compatibility was determined by   FTIR and DSC. Accelerated stability studies were also carried out following ICH Guidelines. SEM revealed that microspheres were found spherical, free flowing and porous. The wall thickness and entrapment efficiency was found in between 86.26 μ & 118.77 μ, 62.12% & 98.29 % respectively. The drug release was extended maximum upto 12hours with cellulose acetate using 1-4 dioxan as solvent and upto 12 hours with cellulose acetate phthalate using 1,4-dioxan and dimethyldigol. FTIR and XRD spectra results showed ciprofloxacin hydrochloride was compatible with excipients. The curve fitting data revealed that the release followed first order kinetics and higuchi’s and peppas plots stated non-fickian and diffusion controlled where dimethyldigol and 1,4 dioxan as solvent polymer showed effect over the size and release kinetics.

Effect of Synergist on Pigment Violet 23

There is a need in the area of solvent dispersion of organic pigments for products of lower viscosity (i.e. fluidity) and improved transparency and gloss. This is especially a need in the area of solvent inks for packaging applications. The solvents in these inks are typically oxygenated types and alcohols (ethanol, propanols), esters (ethyl acetate, isopropyl acetate) and ethers (mono methyl ether of propylene glycol), or mixtures of it. The typical resins dissolved in these solvents for formulating packaging inks are nitrocellulose, polyamide, polyurethane and polyvinyl butyrate.

Preparation of Mono sulphonation of Dioxazine compound is carried out with controlled Degree of Sulphonation like 0.9. After that this mono sulphonated mass is coupled with long chain Amine (C10-C18) and prepared new additive.

Effect of this sulphonated mass and additive is measured by addition into pigments. This effect is measured in solvent base ink application and found that due to effect of this sulphonated mass and additive gives excellent flow with improved gloss and transparency.

Effects of Diminazene Aceturate and Ivermectin Administration on Semen and Serum Parameters of the Red Sokoto Buck

Twenty seven red Sokoto bucks, at the age of 2 years and weighing between 32–34kg were used.  After administration of the drugs, semen and sera samples were collected 1, 24, 72, and 192 hours for analysis.  The parameters studied namely semen volume, percentage motility of sperm, sperm concentration, live sperm percentage, semen glucose level, serum testosterone and serum follicle stimulating hormone were found to decrease significantly (P<0.05) when compared with the pre treatment group throughout the collection period.  However, the drugs did not affect the live sperm percentage and ivermectin did not affect semen glucose level. A relationship was established between spermatological characteristics and serum testosterone and follicle stimulating hormone levels.  These findings indicate that the drugs investigated in this study decreased semen parameters and serum testosterone and follicle stimulating hormone. It was concluded that diminazene aceturate and ivermectin should be used cautiously in red Sokoto bucks meant for breeding due to the deleterious effects they were observed to have on fertility parameters.
