Abstract:- Cassia fistula Linn. Family Fabaceae. commonly known as Aragwadha. Fruit, leaf, dried pulp, bark are used in Ayurveda. Mainly used in constipation, purgative, rheumatism, skin dissorders. The flowers posses’ astringent, purgative, febrifugal and ant biliousness properties. A decoction of the flowers is given in stomach troubles. Till date no detailed scientific study has been done regarding flowers, for the first time flowers are subjected to evaluate its pharmacognostical study and its powder and its micrometric analysis. Pharmacognostical evaluation shows the presence of trichomes, pollen grains, papilous parenchyma, oil globules and prismatic crystal. The micrometric analysis shows pollen grain measures 136.84 µm2 and Prismatic crystal measures 15.48 µm2.
Key words:- Cassia fistula, flower, Pharmacognosy, micrometry.

Abstract:-Nanotechnology is a natural end result of scientific development and our ability to understand and manipulate matter at smaller and smaller level. Current research is directed towards the production of wide array of different nano-scale structures. The fabrication techniques of the structures can be divided into 2 approaches: “top-down” and “bottom-up.” Till date all the articles have mentioned future treatment opportunities of nanotechnology in dentistry that includes local anesthesia, dentition re-naturalization, permanent hypersensitivity cure, complete orthodontic realignment during single office visit, covalently bonded diamondised enamel, and continuous oral health maintenance using mechanical dentifrobots, but none have mentioned nanoproducts that are available and used in dentistry at present. This review article tries to highlight the present scope of nanotechnology in dentistry.

Abstract:- The objective of this study was to screen inhibitory effects of selected herbs on plant growth. The peels of three species of Citrus, Citrus maxima (Burm.f) Merr., Citrus reticulata Blanco and Citrus aurantifolia (Christm.), were selected for various extractions. Three extraction solvents: methanol, 80% methanol and water were used in this study. The test methods were seed germination bioassay which focused on percent inhibition of seed germination, and seedling length bioassay that reflected the inhibitory effects on root elongation of seedling plants of lettuce seeds, Lactuca sativa L with suitable germination and growth rate as the representative for weeds in the test such as sensitivity, simplicity, low cost and suitability. The result showed that the 1 mg/ml of 80% methanol extracts of Citrus aurantifolia had significant inhibitory effects on germination of lettuce seeds. For the seedling length bioassay, three extracts of Citrus aurantifolia had inhibitory effects on root elongation of lettuce seeds with EC10 of 0.01 µg/ml, 0.11 µg/ml, 0.01 µg/ml for MeOH, 80% MeOH and aqueous extracts, respectively. The study is worthy of further investigation since this could provide potential bioherbicide and may lead to the discovery of new effective and applicable bioherbicide.
Keywords:- Citrus spp, seed germination bioassay, seedling length bioassay, bioherbicide.

Abstract: - Background: The objective of our present study was to determine the prevalence of Pseudomonas aeruginosa from various infections and its properties and susceptibility pattern to commonly used antibiotics. Materials and Methods: During a 2-year period, specimens were received from various infections and the same were processed and the Pseudomonas aeruginosa strains isolated using standard microbiological techniques and its properties and antibiogram was studied using 8 antimicrobials. Results: Out of 1810 clinical samples, a total of 168 strains of P. aeruginosa were isolated and the prevalence rate was 9.28%. Maximum number was from samples of pus (55.3%) followed by urine (18.5%). The maximum number of samples from males and the infection was seen maximum among females of age group of 51-60 Yrs.(24.6%) followed by male and female almost equally in the age group of >61Yrs. (21.6% and 22.8% respectively). Fifty six percent of strains produced the pigment pyocyanin(55.35%) followed by Pyoverdin(20.23%). Out 168 strains of Pseudomonas aeruginosa 146 were found Multi Drug Resistant (MDR) strains. Predominant MDR strains isolated from pus 83 (56.85%), urine 24 (16.44%), endo tracheal tubes 16 (10.96%), sputum 10 (6.85%), broncho alveolar lavage 9 (6.16%), ear swabs 4 (2.74%). Pseudomonas aeruginosa has shown resistance to Gentamicin (61.91%), Tobramycin (60.12%), Amikacin (57.74%), Cefixime (88.88%), Ceftazidime (69.64%), Cefoperazone (69.05%), Piperacillin (66.67%), and Carbencillin (41.07%). Conclusion: High prevalence of P. aeruginosa as an opportunistic pathogen has been developing with increased resistance to antimicrobial agents and thus becoming a significant threat.

Abstract:-Prostate Specific Antigen (PSA) has long been used as a biological marker for prostatic cancer. Recent studies have demonstrated that PSA synthesis can be induced in both sexes by steroid hormones including Progesterone. PSA is present in the breast milk and other body fluids and tissues of women in health and in various disease conditions. The massive amounts of steroid hormones produced by the placenta during pregnancy stimulate PSA synthesis in the breast tissue. PSA in breast milk probably plays an important role in post-natal growth and development of the infant by virtue of its IGFBP 3 protease activity liberating IGF-I, its very cationic nature, the inactivation of the Protein C inhibitors and extensive homology of PSA with Tissue kallikrein, gamma Nerve growth factor and Epidermal growth factor binding protein. In this study, PSA levels in breast milk were found to decrease with increasing time post-partum. The milk PSA levels were higher in case of lesser gestation at delivery, smaller birth weight of the baby and for a male baby.
