Objectives: Dhat syndrome is a cultural bound syndrome in which affected individuals have morbid pre-occupation with semen loss in their urine and its impact on the body. Previous studies have explored the symptomatology and perception regarding seminal discharge of such patients while there is lacked of literature on the assessment by quacks and practitioner of alternative and complementary practitioners (ACMP). Therefore, in addition to objectives of previous studies, this study explores the reprehensibility of such practitioners as they may not be giving correct advice to such patients. Methods: For duration of three months, this mixed method study was conducted in Rohilkhand Medical College campus; individuals were approached both in and outside the Psychiatric Outpatient Department using purposive sampling procedure. ICD-10 diagnostic criterion was used to include affected individual in the study sample. Subsequently, a semi-structured questionnaire to document their socio-demographic data and symptomatology was used. Further, previous consultation to quack, ACMPs and allopathic practitioners other than psychiatrist and advice given to the patient by them was obtained via in-depth interview. The quantitative data was analyzed through proportions whereas qualitative data via thematic analysis. Results: There were 38 out of 110 with Dhat syndrome. Invariably, they complained of undue concern regarding debilitating effects of seminal discharge and harmful for the body. A total 21.1% had prior consultation to ACMPs and attributing it to masturbation and hot weather. Surprisingly, allopathic practitioners consulted gave incorrect advices. Conclusion: Dhat syndrome affects individuals irrespective of their social and education background. Sex education among the masses and emphasis for awareness of this syndrome among ACMPs and allopathic practitioners other than psychiatrist is necessary to reduce this cultural bound syndrome.

AIMTo evaluate the possible antifertility activity of Sarcostemma acidum (Roxb) Voigt. stem extract in male rats.

METHODMale rats were given 70% methanol extract of S. acidum stem orally at dose levels of 50 and 100 mg/kg/day for 60 days. Fertility was evaluated with mating test. Sperm motility and sperm density in cauda epididymides were also assessed. Biochemical and histological analyses were performed on blood samples and on the reproductive organs.

RESULTSS. acidum stem extract resulted in an arrest of spermatogenesis without any systemic side effect. Sperm motility as well as sperm density was reduced significantly. Treatment caused a 80% reduction in fertility at the 50 mg dose and complete suppression of fertility at the 100 mg dose. There was no significant change in RBC and WBC count, hemoglobin, haematocrit, sugar and urea in the whole blood and cholesterol, protein and phospholipid in the serum. The protein and glycogen content of the testes, fructose in the seminal vesicle and protein in epididymides were significantly decreased. Cholesterol in the testes was elevated. Treatment at both of the doses caused a marked reduction in the number of primary spermatocytes (preleptotene and pachytene), secondary spermatocytes and spermatids. The number of mature Leydig cells was decreased, and degenerating Leydig cells was increased proportionately.

CONCLUSIONS. acidum stem extract arrests spermatogenesis in male rats without noticable side effects.

OBJECTIVEToxic metal ions have been implicated in the generation of reactive oxygen species (ROS) and nitric oxide (NO). Metallothionines (MT) and plant flavonoids have been reported in the intervention against oxidative damage. We investigated the effect of zinc induced MT and green tea polyphenol (GTP) in reducing the oxidative responses induced by nickel and platinum.

METHODSZinc (10 mg/kg b. wt, sc) was administered to rats twice at a gap of 24 hrs and GTP (10 mg/100 mL in drinking water) was fed ad libitum for 8 days. Nickel chloride (150 umol/kgb.wt, ip) and cisplatin (50 mumol/kg b.wt, sc) was administered to rats 24 h after Zn or GTP pre-treatment. Animals of all the groups were sacrificed 16 hrs after treatment and biochemical markers for toxicity were monitored.

RESULTSZinc or GTP pre-treatment caused significant protection against nickel or cisplatin enhanced mortality in rats, and reduction in lipid peroxidation and NO.

CONCLUSIONIt is proposed that inhibition of ROS and NO by GTP and zinc may prove useful as a selective pharmacological agent in the amelioration of metal toxicity.

Background: Lignocaine with adrenaline is routinely used as a local anesthetic for dental procedures. Adrenaline was added to increase the duration of anesthesia. However, epinephrine containing a local anesthetic solution is not recommended in conditions such as advanced cardiovascular diseases and hyperthyroidism. Recently, ropivacaine has gained popularity as a long-acting anesthetic with superior outcomes. The goal of this study was to assess and compare the effectiveness of 0.75% ropivacaine alone and 2% lignocaine with adrenaline (1:80,000) in the removal of bilateral maxillary wisdom teeth using the posterior superior alveolar nerve block technique. Methods: This was a single-blind, randomized, split-mouth, prospective study assessing 15 systemically sound outpatients who needed bilateral removal of maxillary third molars. We randomly allocated the sides and sequences of ropivacaine and lignocaine with adrenaline administration. We evaluated the efficacy of both anesthetics with regard to the onset of anesthesia, intensity of pain, variation in heart rate, and blood pressure. Results: The onset of anesthesia was faster with lignocaine (138 s) than with ropivacaine (168 s), with insignificant differences (p = 0.001). There was no need for additional local anesthetics in the ropivacaine group, while in the lignocaine with adrenaline group, 2 (13.3%) patients required additional anesthesia. Adequate intraoperative anesthesia was provided by ropivacaine and lignocaine solutions. No significant difference was observed in the perioperative variation in blood pressure and heart rate. Conclusion Ropivacaine (0.75%) is a safe and an adrenaline-free local anesthetic option for posterior superior alveolar nerve block, which provides adequate intraoperative anesthesia and a stable hemodynamic profile for the removal of the maxillary third molar.

The phylogenetic relationships of the most dominant and morphologically cryptic endophytic fungal isolates from each of five selected medicinal plants, namely Potentilla fulgens, Osbeckia stellata, Osbeckia chinensis, Camellia caduca, and Schima khasiana of the biodiversity rich state of Meghalaya, were assessed with random amplification of polymorphic DNA and PCR-restriction fragment length polymorphism profiles. Sequencing of the internal transcribed spacer 1, small subunit rRNA and partial beta-tubulin gene fragments was also conducted to determine the phylogenetic relationships of these isolates with fungal sequences available in Genbank, NCBI. The identity of the fungal isolates is suggested based on the molecular phylogenetic data.

Fifty three fungi isolated from soils of different microhabitats of eastern Himalayan range (3,400~3,600 msl) were screened for mycosynthesis of silver nanaoparticles (AgNPs) and their efficacy as antimicrobials were assessed in combination with commonly used antibiotics. Three isolates Aspergillus terreus SP5, Paecilomyces lilacinus SF1 and Fusarium sp. MP5 identified based on morphological and 18S rRNA gene sequences were found to synthesize AgNPs. These nanoparticles were characterized by visual observation followed by UV-visible spectrophotometric analysis. The AgNPs synthesized by Aspergillus terreus SP5, Paecilomyces lilacinus SF1 and Fusarium sp. MP5 showed absorbance maxima at 412, 419, and 421 nm respectively in the visible region. Transmission electron microscopy micrograph showed formation of spherical AgNPs of 5~50 nm size. The antimicrobial activity of the mycosynthesized nanoparticles were investigated alone and in combination with commonly used antibiotics for analysis of growth inhibition zone against test organisms, namely, Staphylococcus aureus MTCC96, Streptococcus pyogenes MTCC1925, Salmonella enterica MTCC735 and Enterococcus faecalis MTCC2729. The mycosynthesized nanoparticles showed potent antibacterial activity and interestingly their syngergistic effect with erythromycin, methicillin, chloramphenicol and ciprofloxacin was significantly higher as compared to inhibitions by AgNPs alone. The present study indicates that silver nanoparticles synthesized using soil borne indigenous fungus of high altitudes show considerable antimicrobial activity, deserving further investigation for potential applications.

In the present study, an attempt to evaluate the antimicrobial and antioxidant activity of fungal endophytes inhabiting Emblica officinalis has been made keeping in view the medicinal importance of the selected host plant in Indian traditional practices. A total of four endophytic fungi belonging to Phylum Ascomycetes were isolated from different parts of the plant which were characterized morphologically and by using rDNA-internal transcribed spacer. The most frequently isolated endophyte was Phomopsis sp. The antioxidant activity by 2, 2-diphenyl-1-picrylhydrazyl (DPPH) and reducing power assay, and total phenol were evaluated using ethanolic extract of endophytic fungi. DPPH activities in all the ethanolic extract increased with the increase in concentrations. Endophytes, Phomopsis sp. and Xylaria sp. showed highest antioxidant activity and also had the higher levels of phenolics. Antimicrobial activity of fungal extract were tested against four bacteria namely, Escherichia coli MTCC730, Enteroccocus faecalis MTCC2729, Salmonella enterica ser. paratyphi MTCC735 and Streptococcus pyogenes MTCC1925, and the fungus Candida albicans MTCC183. In general, the fungal extracts inhibited the growth of test organisms except E. coli.

Very few studies have addressed the phylogenetic diversity of fungi from Northeast India under the Eastern Himalayan range. In the present study, an attempt has been made to study the phylogenetic diversity of culturable soil fungi along the altitudinal gradients of eastern Himalayas. Soil samples from 24 m above sea level to 2,000 m above sea level altitudes of North-East India were collected to investigate soil micro-fungal community structure and diversity. Molecular characterization of the isolates was done by PCR amplification of 18S rDNA using universal primers. Phylogenetic analysis using BLAST revealed variation in the distribution and richness of different fungal biodiversity over a wide range of altitudes. A total of 107 isolates were characterized belonging to the phyla Ascomycota and Zygomycota, corresponding to seven orders (Eurotiales, Hypocreales, Calosphaeriales, Capnodiales, Pleosporales, Mucorales, and Mortierellales) and Incertae sedis. The characterized isolates were analysed for richness, evenness and diversity indices. Fungal diversity had significant correlation with soil physico-chemical parameters and the altitude. Eurotiales and Hypocreales were most diverse and abundant group of fungi along the entire altitudinal stretch. Species of Penicillium (D = 1.44) and Aspergillus (D = 1.288) were found to have highest diversity index followed by Talaromyces (D = 1.26) and Fusarium (D = 1.26). Fungal distribution showed negative correlation with altitude and soil moisture content. Soil temperature, pH, humidity and ambient temperature showed positive correlation with fungal distribution.

Meghalaya, (in India), in the region of the mega-biodiversity hotspots, is home to a plethoraof wild mushrooms. The present study concerns the exploration of the order Agaricales,which includes rare gilled mushrooms considered endangered under IUCN A4c criteria, dueto the declining habitat. Electron microscopy of the gill sections revealed an abundance ofclamp connections, hyphal cell walls, cystidia, and basidia. This rare species which belongsto the family Cyphellaceae, exhibits morphological and molecular differences from theCyphella spp. Phylogenetic analysis revealed that it formed a clade under the genusCampanophyllum of the order Agaricales, confirmed by both Neighbor Joining (NJ) andBayesian phylogenetic analysis. Being nutritionally potent along with its efficient antioxidantvalue, the fungal extract shows significant rise of two-fold in the antimicrobial activity alongwith the commercial antibiotics. The compound, Phenol, 2, 4-bis (1, 1-Dimethylethyl) (2, 4-DTBP) showed in ample range in the fungal extract along with aliphatic hydrocarbons,terpene, alcohol and volatile organic compounds on further characterization in GCMS. Thepresent study indicates the endangered Campanophyllum proboscideum could be a richsource of natural antioxidants and an effective pharmaceutical agent.
