Insecticidal property of Ocimum essential oil embedded polylactic acid packaging films for control of Sitophilus oryzae and Callosobruchus chinensis.

Naturally derived essential oils (EOs) from Ocimum basilicum (OB) and Ocimum gratissimum (OG) were incorporated in polylactic acid (PLA) matrix with concentration of 2.5 % and 5 % respectively by solvent casting method, with an aim to develop insecticidal polymer pouches (insect proof polymer pouches). The major components following GC-MS analysis revealed the presence of EOs as estragole (69.998 %) in OB and thymol (29.843 %) in OG. The developed films with EOs showed remarkable insecticidal activity with 100 % and 80 % mortality rate for OB and OG respectively at 2.5 % concentration against rice weevil (Sitophilus oryzae). While, both OB and OG EOs observed 100 % mortality against pulse beetle (Callosobruchus chinensis) after 96 h exposure in presence of grain conditions and the insecticidal efficacy was equivalent to the commercial hermetic bags (CSB). The physical property of film showed increase in the film thickness in EO-PLA films whereas the mechanical properties of EO-PLA films matrix have increased the polymer flexibility with decreasing tensile strength (TS) and Youngs modulus (EM) as TS OB 5 %, OG 5 % - 15.64 MPa, 17.66 MPa respectively. While, water vapour transmission rate (WVTR) was reduced to 0.015 g/m2.hr, optical characteristics showed slight significant change in colour and FTIR spectra exhibited a change in -OH stretching compared to blank PLA matrix. The surface morphology of the blank and EO embedded PLA films visualized by SEM depicted a complete homogenization of essential oils in the PLA matrix.

A Rare Case Report of an Acute Orbit.

Orbital complications of rhino-sinusitis was one of the most common extracranial complications in the pre-antibiotic era. However, the incidence of intra-orbital complications secondary to rhinosinusitis has significantly decreased in recent times with the advertent usage of broad-spectrum antibiotics. The subperiosteal abscess is one of the most common intraorbital complications of acute rhinosinusitis. This is a case report of a 14-year-old girl who presented with diminished vision and ophthalmoplegia which on evaluation was diagnosed to be a case of a subperiosteal abscess. The patient was treated by endoscopic sinus surgery and with complete post-operative recovery to normal vision and ocular movements. This report aims at describing the presentation and management of the condition.

Prevalence of preoperative anxiety in patients posted for surgical procedures and its relation to the doses of anesthetic drugs: A cross-sectional study.

Background: In patients undergoing surgical procedures, preoperative period is one of the most worrying periods. There are only few studies which revealed that increased preoperative anxiety is associated with increased requirements of doses of anesthetic agents. Aim: The aim of this study is to assess the prevalence of preoperative anxiety in patients posted for surgical procedures and its relation to the doses of anesthetic drugs. Materials and Methods: This is a cross-sectional, analytical study done between January 2021 and April 2021. A total of 100 patients undergoing surgery have given consent to participate in the study by filling self-designed questionnaire, Amsterdam Preoperative Anxiety and Information Scale (APAIS). Data analysis was done by SPSS version 24 using appropriate statistical tests. Results: Preoperative anxiety was noted in 21% of the patients who were undergoing surgery. The association between preoperative anxiety and need for increase in the doses of anesthetic agents during intraoperative period was found to be statistically significant (P < 0.004). Conclusion: A significant number of patients required increased amounts of anesthetic drugs to reduce anxiety during intraoperative period. Therefore, appropriate methods have to be introduced to address the concerns of patients undergoing surgery and thereby reducing anxiety.

Hyoid Chondroma.

Mass lesions of the larynx are one of the most common clinical entity which we come across in routine otorhinolaryngology and head neck practice with varied symptomatology. Among all the mass lesions of the larynx, Epithelial neoplasms constitute up to 97%. Mesenchymal tumours of the larynx constitute only 0.3-1.0% of all the laryngeal tumors. Abundance of cartilage structures in the larynx made it a spot for mesenchymal tumors [chondromas and chandrosacrcomas]. The spectrum of mesenchymal neoplasms can vary from chondromas, chondroblastoma to chondrosarcoma. Here we want to share our experience of a mesenchymal tumour of the larynx. This case is reported for the rarity and ambiguity in diagnosis. Though these are slow-growing tumours with an early presentation, in our case, the patient had a supportive tracheostomy without definitive treatment for more than 2 years. We managed this patient by excising the mass by lateral pharyngotomy with the preservation of larynx followed by successful Decannulation in 20 days.

Management of Cervical Tracheo-Esophageal Fistula by Lateral Cervical Approach: Our Experience'.

Acquired Tracheo-esophageal fistula (TEF) is a challenging and complicated condition. The laryngeal protection is lost in acquired TEF cases due to the established connection between the esophagus and the airways leading to aspiration, pneumonia, and acute respiratory distress syndrome. Malignancy contributes to about 80% of acquired TEF. Nonmalignant causes for TEF include prolonged ventilation, trauma (iatrogenic, penetrating, or blunt injury), foreign bodies, corrosive burns, and granulomatous infections. With the advancements in critical care, the incidence of TEF post-ventilation is on the rise in recent decades. We would like to share our experience managing ten cases of nonmalignant acquired cervical TEF by the lateral cervical approach at our institute. Apart from the isolated TEF cases, one patient with concomitant tracheal stenosis was repaired simultaneously with good postoperative results. TEF was identified in two cases following removal of T-tube and solid stent respectively and was repaired successfully with lateral cervical approach with strap muscle flap interposition.

Assessment of biogrowth assemblages with depth in a seawater intake system of a coastal power station.

Marine biogrowth infestation of a seawater intake system was investigated. A digital camera fixed onto a skid was used to record the biogrowth at intervals of 5 m up to a depth of 55 m. Divers inspected the intake shaft and collected the biogrowth samples for biomass estimation. A biomass density of 7.5 kg m-2 and 28.2 kg m-2 was recorded at 5 and 30 m depths respectively. Inspection by the divers revealed that hard-shelled organisms such as oysters and brown and green mussels were observed in plenty up to a thickness of 15 cm and bryozoans grew as epibionts. At lower depths (<40 m), hydroids grew on the shells of green mussels along with silt accumulation. The biofouling community was composed of 46 organisms, exhibiting variation in distribution and abundance. The study explains the extent and type of marine biogrowth phenomena with depth and describes biofouling preventive methods.Supplemental data for this article is available online at https://doi.org/10.1080/08927014.2021.1933457 .

Perceived stress, anxiety, and coping states in medical and engineering students during examinations.

AIM: This study aims to study the factors associated with stress, anxiety, and coping states in students of 1st and 2nd year in medical and engineering colleges during examinations. MATERIALS AND METHODS: This prospective, longitudinal study was conducted on 200 undergraduate medical and engineering students from 1st to 2nd year (50 in each year), after obtaining ethical approval from the institutional ethics committee. All the participants gave written informed consent. All students filled a questionnaire which consisted of a general information sheet, perceived stress scale, Hamilton Anxiety Rating Scale, brief COPE inventory, and sources of stress questionnaire 1 month before and 1 month after their university examinations. Data were analyzed using t-test, Mann-Whitney U-test, Kruskal-Wallis test, and Chi-square test as appropriate. RESULTS: In medical students, perceived stress was significantly higher in those in the management quota (both years), living in shared accommodation and from nuclear family (1st year) and male (2nd year). Only accommodation had a statistically significant relationship with perceived stress in 2nd year engineering students. A statistically significant association of perceived stress and anxiety with academic performance was observed. Anxiety in students was significantly more before the examination compared to after the examination. The association of all the coping strategies used, with the academic performance, was statistically significant. CONCLUSIONS: In both medical and engineering students, there was a significant association of perceived stress and anxiety with academic performance. Both medical and engineering students used active coping a little more than avoidant coping strategies during the examination time. The association of all the coping strategies used, with the academic performance, was statistically significant, thereby proving the importance of coping states in academic performance.

Suitable Alternative for Human Cadaver Temporal Bone Dissection: Comparative Micro Ear Anatomy of Cattle, Pig and Sheep with Human.

The study was undertaken to compare the micro ear anatomy of three commonly available animal models which are expected to have similar anatomy to human and to find out suitable model among them as an alternative for human cadaver temporal bone dissection. This is an observational study of comparison of micro ear anatomy of the three animal models with human. Decapitated heads of cattle, pig and sheep were collected from slaughter houses, soft tissues along with brain were removed and preserved in commercially available formalin preservative. CT scan was taken for the three specimens and 3D reconstructions were done. Each specimen was subjected to micro dissection and the anatomical features were studied and compared with human. Among the three animal models sheep is found to be an ideal model for a beginner because of ease of exposure of bone, very thin cortical bone, and no cellularity, good exposure of all the middle ear structures and similar interrelations of middle ear structures with human. Pig may not be an ideal model because of abundant fatty soft tissues, thick periosteum very narrow space occupied by the middle ear, difficulty in accessing cellularity small fragile ossicular chain and overhanging facial nerve.

Recurrent angiofibroma of ethmoid region - a rare variant.

The common variant of angiofibromas of head and neck region is juvenile nasopharyngeal angiofibroma (JNA). However extranasopharyngeal angiofibromas (ENAF) occurs very rarely at any age in either sex, and they differ from classical JNA in incidence, clinical and radiological presentation. They form the differential diagnosis for any mass nose or nasal polyp. We present a case of recurrent angiofibroma of ethmoid region presented with recurrent lesion with bilateral proptosis and bossing of forehead. MRI showed involvement of bilateral nasal cavities, ethmoids and frontal sinuses with erosions of ethmoid roof and posterior table of frontal sinuses. Entire mass was excised by craniofacial resection which was histopathologically confirmed as Angiofibroma.

Conflict of interest - serious issue on publication ethics for Indian medical journals.

INTRODUCTION: There are several vested interest lies on research publication hence the editorial policy is the sole important factor to control and regulate ethical publications in medical sciences especially on 'conflict of interest' issue. The study was aimed to assess on awareness of 'conflict of interest' issue in medical research and publication among the editorial staff, peer reviewers and authors of Indian medical journals. METHODS: Total 61 authors who have published research articles recently in Indian medical journals from 2008-2012, 56 peer reviewers who reviewed the manuscripts during same period and 35 editorial board members of various Indian medical journals were assessed by questionnaire and telephone interview regarding their understanding and knowledge on 'conflict of interest' issue for ethical publication. RESULTS: Only seven (12%) of the authors knew about the 'conflict of interest' issue and 11 (19%) of the medical authors have just heard about it. Out of 12% of authors who knew 'conflict of interest' issue only 15% provided that statement to the journals. Among the peer reviewers only 17 (30%) knew about 'conflict of interest' of which 51 (91.5%) stated that they do not bother about this issue while reviewing the manuscripts. But interestingly 42 (75%) of the peer reviewers confessed that they had a bias on the topics written by their friends or students. Among the editorial board members of Indian medical journals only 14 (25%) have any idea on 'conflict of interest issue'. CONCLUSIONS: Results clearly shows poor understanding of 'conflict of interest' like important ethical issue among Indian medical scientists or journals.

Development and application of active films for food packaging using antibacterial peptide of Bacillus licheniformis Me1.

AIMS: An attempt was made to evaluate the effectiveness of partially purified antibacterial peptide (ppABP) produced by Bacillus licheniformis Me1 for food preservation by means of active packaging. METHODS AND RESULTS: The active packaging films containing ppABP were developed using two different packing materials [low-density polyethylene (LDPE) and cellulose films] by two different methods: soaking and spread coating. The activated films showed antibacterial activity against pathogens. The release study of ppABP from coated film showed that the LDPE films liberated ppABP as soon as it comes in contact with water, while gradual release of coated ppABP was observed in case of cellulose films. The activated films showed residual activity in different simulating conditions, such as pH of food and storage temperatures. The activated films demonstrated its biopreservative efficacy in controlling the growth of pathogens in cheese and paneer. CONCLUSIONS: The ppABP-activated films were found to be effective for biopreservation. The ppABP from active films got diffused into the food matrix and reduced the growth rate and maximum growth population of the target micro-organism. SIGNIFICANCE AND IMPACT OF THE STUDY: Both types of ppABP-activated films can be used as a packaging material to control spoilage and pathogenic organisms in food, thereby extending the shelf life of foods.

Antidiabetic Effect of GII Compound Purified from Fenugreek (Trigonella foenum graecum Linn) Seeds in Diabetic Rabbits.

Aim is to study the antidiabetic effect of a compound GII purified earlier from the water extract of fenugreek (Trigonella foenum graecum) seeds by Murthy and his colleagues (patented in India and USA) in diabetic rabbits. Diabetes was induced in rabbits by injecting 80 mg/kg bw of alloxan intravenously into rabiits. Rabbits were subdivided into subdiabetic [fasting blood sugar (FBG) up to 120 mg/dl with abnormal glucose tolerance in glucose tolerance test (GTT)], moderately diabetic (FBG below 250 mg/dl) and severely diabetic (FBG above 250 mg/dl). Blood glucose and glycosylated hemoglobin (HbA1C) were estimated by procedures in the kits of Stangen Immunodiagnostics, Mumbai using, respectively, glucose oxidase method and absorbance at 415 nm. Serum insulin was estimated by the ELISA method as described in the kit of Boehringer Mannheim Immunodiagnostics, Mumbai, India. GII was found to improve blood glucose utilization in GTT and reduced FBG and HbA1C. In the present communication detailed studies were carried out with GII in the subdiabetic, moderately diabetic and severely diabetic rabbits. GII at a dose of 50 mg/kg bw per day brought down the elevated FBG levels in the untreated subdiabetic (FBG 96.6 ± 7 mg/dl), moderately diabetic (150.1 ± 14 mg/dl) and severely diabetic rabbits (427 ± 46 mg/dl) to normal in 12, 15 and 28 days of treatment. It improved serum HbA1C and insulin levels also in these rabbits. Intermittent therapy once a week for 6 weeks with GII at the same dose brought down the FBG values to normal in the subdiabetic (FBG 96.0 ± 2 mg/dl) and in the moderately diabetic rabbits to 133.0 ± 12 mg/dl. After stopping therapy of the subdiabetic and moderately diabetic rabbits whose FBG values came to normal after treatment with GII 50 mg/kg bw, the values remained normal for 1 week and showed a tendency to increase only after 15 days. If these animal studies are applicable to humans these results indicate that a diabetic person need not take GII daily when once the FBG value comes to normal or near to normal. Patients might be able to take GII only when the FBG value shows tendency to increase. So, intermittent therapy is possible with the potent product GII of the fenugreek seeds which is of a great advantage.

Glycine soya diet synergistically enhances the suppressive effect of tamoxifen and inhibits tamoxifen-promoted hepatocarcinogenesis in 7,12-dimethylbenz[α]anthracene-induced rat mammary tumor model.

There is increasing interest in phytoestrogens as potential alternatives to synthetic selective estrogen receptor modulators (SERMs) in the prevention and therapy of breast cancer. The present study is aimed at determining whether dietary glycine soya (Glycine max seeds; GS), which is rich in phytoestrogens, can enhance the anti breast cancer efficacy of the SERM tamoxifen (TAM) and the effect of TAM and GS, either alone or in combination, on DMBA-initiated hepatocarcinogenesis in rat. For determination of enhancing effect, rats bearing palpable 7, 12-dimethylbenz[α] anthracene (DMBA)-induced mammary tumors were treated with TAM (10 mg kg(-1)/day) while being fed AIN-93G diet with or without added GS (3×10(4) mg kg(-1)), and the tumor growth was monitored up to 5 weeks of treatment. For determining the effect on hepatocarcinogenesis, DMBA-initiated rats were exposed to TAM and dietary GS as above for 6 weeks during promotion stage in a medium-term bioassay, and the development of placental form of glutathione-S-transferase (GST-P)-expressing preneoplastic liver lesions was quantified. Exposure to both TAM and dietary GS enhanced the anti tumor efficacy of TAM via a combination of tumor cell apoptosis (determined by TUNEL) and inhibition of tumor cell proliferation (determined by PCNA immunostaining) and suppressed the growth of GST-P-positive liver lesions. The findings show that dietary GS enhances the therapeutic efficacy of TAM against mammary tumors and minimizes TAM's hepatocarcinogenesis promotion potential.

Mechanism of Antidiabetic Action of Compound GII Purified from Fenugreek (Trigonella foenum graecum) Seeds.

To study the mechanism of action of water soluble compound GII purified from fenugreek (Trigonella foenum graecum) seeds which was shown earlier to have antidiabetic effect in the subdiabetic, moderately and severely diabetic rabbits. In rabbits (1-1.5 kg bw) diabetes was induced by intravenous injection of 80 mg/kg bw of alloxan. They were fed with GII at a dose of 50 mg/kg bw daily once in the morning for 15 days in the subdiabetic and moderately diabetic and 30 days in the severely diabetic rabbits. Serum total cholesterol (TC), triglycerides (TG), LDL + VLDL cholesterol [(LDL + VLDL)C], HDL cholesterol [(HDL)C], total tissue lipids, glycogen and enzymes of carbohydrate metabolism (glycolysis, gluconeogenesis, polyol pathway) hexokinase, glucokinase, pyruvate kinase, malic enzyme, glucose-6-phosphatase, glucose-6-phosphate dehydrogenase, aldose reductase and sorbitol dehydrogenase and antioxidant enzymes glutathione peroxidase, glutathione reductase and superoxide dismutase were estimated. Liver and kidney function parameters were also estimated. Treatment with GII for 15 days in the subdiabetic and moderately diabetic rabbits and for 30 days in the severely diabetic rabbits (i) decreased the elevated lipids TC, TG, (LDL + VLDL)C and increased the decreased (HDL)C, (ii) decreased the elevated liver and heart total lipids, TC and TG, (iii) increased the decreased liver and muscle glycogen, (iv) increased the decreased hexokinase, glucokinase, pyruvate kinase, malic enzyme, glucose-6-phosphate dehydrogenase, superoxide dismutase, glutathione peroxidase, (v) decreased the increased glucose-6-phosphatase, sorbitol dehydrogenase, aldose reductase. Results thus show that treatment with GII compound purified from fenugreek seeds for 15 days in the subdiabetic and moderately diabetic and 30 days in the severely diabetic rabbits corrects the altered serum lipids, tissue lipids, glycogen, enzymes of glycolysis, gluconeogenesis, glycogen metabolism, polyol pathway and antioxidant enzymes. Histopathological abnormalities (fatty infiltration and other cellular changes) seen in the pancreas, liver, heart and kidneys were repaired after treatment with GII. In fact partially damaged pancreas was repaired. Liver and kidney function test results were normal in the GII treated animals indicating that GII treatment is safe and free from any side effects.

Anti-hyperglycemic compound (GII) from fenugreek (Trigonella foenum-graecum Linn.) seeds, its purification and effect in diabetes mellitus.

An anti-hyperglycemic compound named GII was purified from the water extract of the seeds of fenugreek (T. foenum-graecum) and shown to be different from trigonelline and nicotinic acid isolated earlier from the same plant. GII (50 mg/kg body weight, po) reduced blood glucose in glucose tolerance test (GTT) in the sub-diabetic and moderately diabetic rabbits and significantly reduced the area under the curve (AUC) of GTT. Treatment for 7 days of the sub-diabetic rabbits with GII (50 mg/kg body weight, po) improved glucose tolerance without reducing fasting blood glucose (FBG) which was nearly normal. The results suggest that there is no risk of hypoglycemia in near normal animals (may be humans also) with abnormal GTT. Treatment of the moderately diabetic rabbits with GII (100 mg/kg body weight for 3 weeks) reduced FBG to nearly normal value and improved GTT. GII was more effective than the standard drug tolbutamide. Intermittent therapy given on days 1-5, 11-15, 26-30 and 56-60 to moderately diabetic rabbits leaving in between days without treatment brought down FBG to normal and AUC during GTT was normal. After 15 days treatment with GII (100 mg/kg body weight for 3 weeks) glycosylated hemoglobin came down and insulin increased to normal values in the sub-diabetic, moderately diabetic and severely diabetic rabbits. GII treatment (100 mg/kg body weight for 15 days) brought down all the altered serum lipids (TC, HDLC, TAG, PLs and FFAs) to normal levels. The results suggest that intermittent therapy, instead of daily therapy is possible and GII has good potential as an oral anti-diabetic drug with intermittent therapy.

Mechanism of anti-diabetic action, efficacy and safety profile of GII purified from fenugreek (Trigonella foenum-graceum Linn.) seeds in diabetic animals.

Mechanism of action of GII (100 mg/kg body weight, po for 15 days) purified from fenugreek (T. foenum-graecum) seeds was studied in the sub-diabetic and moderately diabetic rabbits. In the sub-diabetic rabbits it did not change much the content of total lipids, glycogen and proteins in the liver, muscle and heart (glycogen was not studied in the heart). However, in the moderately diabetic rabbits same treatment decreased total lipids more in the liver (21%) than those in the heart and muscle. Total protein content increased (14%) in the liver but negligible change (5-7%) was observed in heart and muscle. Glycogen increased (17%) in the liver but not in the muscle of the moderately diabetic rabbits (glycogen was not estimated in the heart). Among the enzymes of glycolysis, activity of glucokinase was not affected in the liver of both the sub-diabetic and moderately diabetic rabbits. Phosphofructokinase and pyruvate kinase activity in both sub-diabetic and moderately diabetic rabbits increased (13-50%) indicating stimulation of glycolysis. The activity of gluconeogenic enzymes glucose-6-phosphatase and fructose-1,6-diphosphatase of the sub-diabetic rabbits decreased in the liver (15-20%) but not in the kidneys. In the moderately diabetic rabbits after treatment with GII, glucokinase in the liver was not affected much (-9%) but increased well in the muscle (40%). Phosphofructokinase and pyruvate kinase were moderately increased both in the liver and the muscle (18-23%). The gluconeogenic enzyme glucose-6-phosphatase decreased reasonably well in the liver and kidneys (22, 32%). Fructose-1,6-diphosphatase decreased only slightly (10, 9%) in the moderately diabetic rabbits. Thus GII seems to decrease lipid content of liver and stimulate the enzymes of glycolysis (except glucokinase) and inhibit enzymes of gluconeogenesis in the liver of the diabetic especially moderately diabetic rabbits.

Pseudoepitheliomatous, keratotic, and micaceous balanitis.

A 51-year-old circumcised male presented with hard, thick, keratotic, nail-like covering of the skin of his glans penis of 2 year duration. Histology showed acanthosis, papillomatosis, and elongated rete ridges into the dermis suggestive of pseudoepitheliomatous, keratotic, and micaceous balanitis with features of cellular atypia. Partial penile amputation was done. There was no recurrence after 6 months of follow up.

Insulinotropic effect of cinnamaldehyde on transcriptional regulation of pyruvate kinase, phosphoenolpyruvate carboxykinase, and GLUT4 translocation in experimental diabetic rats.

Diabetes mellitus is a chronic metabolic disorder affecting about 6% of population worldwide with its complications and is rapidly reaching epidemic scale. Cinnamomum zeylanicum is widely used in alternative system of medicine for treatment of diabetes. In the present study, we have performed bioassay guided fractionation of chloroform extract of C. zeylaniucm and identified cinnamaldehyde (CND) as an active principle against diabetes. In continuation to it, a detailed study was undertaken to elucidate its mode of antidiabetic action in STZ induced diabetic rats. Oral administration of CND (20 mg/kg bw) to diabetic rats for 2 months showed significant improvement (p<0.001) in muscle and hepatic glycogen content. In vitro incubation of pancreatic islets with CND enhanced the insulin release compared to glibenclamide. The insulinotropic effect of CND was found to increase the glucose uptake through glucose transporter (GLUT4) translocation in peripheral tissues. The treatment also showed a significant improvement in altered enzyme activities of pyruvate kinase (PK) and phosphoenolpyruvate carboxykinase (PEPCK) and their mRNA expression levels. Furthermore, the median lethal dose (LD(50)) of CND could not be obtained even at 20 times (0.4 g/kg bw) of its effective dose. With the high margin of safety of CND, it can be developed as a potential therapeutic candidate for the treatment of diabetes.

Therapeutic effect of centchroman alone and in combination with glycine soya on 7,12-dimethylbenz[alpha]anthracene-induced breast tumor in rat.

Centchroman is a non-steroidal oral contraceptive and has been found to be a candidate drug for breast cancer exhibiting partial to complete remission of lesions in 40.5% of breast cancer patients. The therapeutic efficacy of centchroman was monitored alone and together with glycine soya on growth of 7,12-dimethylbenz[alpha]anthracene-induced breast tumor in rat. The tumor regression was monitored at different doses of centchroman alone ranging from 0 to 10 mg kg(-1) and with glycine soya from 1x10(4) to 5x10(4) mg kg(-1) per day until 5weeks treatment. An optimum tumor treatment opus was established with varying treatment parameters including doses of therapeutic agents and treatment period. The tumors were found to be static with a strong anti-estrogenic effect. Overall our study shows that both centchroman and glycine soya alone and jointly combat with breast cancer.

Osteogenic activity of constituents from Butea monosperma.

Phytochemical investigation from the stem bark of Butea monosperma, led to the isolation and identification of three new compounds named buteaspermin A (1), buteaspermin B (2) and buteaspermanol (3), along with 19 known compounds. The structure of compounds 1-22 were established on the basis of their spectroscopic data. The isolated compounds 2-17 were evaluated using neonatal (1-3 day old) rat calvaria derived primary osteoblast cultures. Five of these compounds 7, 10-13 showed promising osteogenic activity, attributed to increased osteoblast proliferation, differentiation and mineralization as evidenced by marked increase in expression of alkaline phosphatase, an early phase differentiation marker, and alizarin Red S staining of osteoblasts cultured for 48 h and von Kossa silver staining of nodules formed 15 days after culture with these compounds. Quantification of mineralization by optical density measurement of Alizarin Red S extracted from stained osteoblasts cultured for 7 days in presence of these compounds showed significant (P<0.05, vs corresponding vehicle control group) increase in mineralization. On the basis of biological results, structure-activity relationships are discussed.
