SCREENING AND CHARACTERISATION OF SIDEROPHORE PRODUCING RHIZOBACTERIA FROM PADDY FIELD OF POONDI

To enhance the crop production and to manage plant diseases, many chemicals are being used. The use of such agrochemicals is hazardous to environment. To identify a viable alternate, biocontrol agent is necessary. Keeping this in point, the present investigation was undertaken to isolate PGPR bacteria from paddy rhizospheric soil. A total of 100 bacteria were isolated. On the basis of morphological, physiological and biochemical characterisation most of the isolates belong to Pseudomonas aeruginosa. The isolates were further screened for siderophores production by CAS method. In this 10 isolates showed positive results in siderophore production. The produced siderophore were further characterised based on their classi?cation such as hydroxylate, catecholate and carboxamate depending on the iron ligating group. In the present study, the effect of culture media components in the yield of siderophore was studied. Among the 10 isolates, 3 of were produced catecholate type of siderophore ef?ciently in succinate medium at neutral pH in low iron concentration. Potential siderophore producing isolates was further applied on Vigna radiata (Green gram). There was a signi?cant increase in the shoot and root length by roll towel method and Pot assay method

Morphometric Study Of Bony Palate Among Dry Skulls Of South India Population

Background: Hard palate forms an important area in the skull, between the oral cavity and the nasal cavity. It isformed anteriorly by the palatine process of maxillae and posteriorly by the horizontal plates of palatine bonesof both sides, forming a cruciform suture in the midline. The hard palate play a crucial role in articulation ofspeech and any significant variations in its morphology may lead to alterations in the speech of an individual.Materials and Methods: The present study was conducted on 50 dry skulls of unknown sex and age obtained fromthe department of Anatomy, K S Hegde Medical Academy, Mangaluru. Various morphometric measurments weretaken from the skull using digital vernier calipers.Results: The length, breadth and height of the hard palate was 50.45mm±2.86mm, 39.38mm±2.28mm and10.31mm±2.21mm respectively. The distance between the greater palatine foramen and middle maxillary suturewas 14.80mm±1.14mm on right and 14.83mm±1.08mm on left side. The position of greater palatine foramen in82% of the skulls was opposite 3rd molars and 18% was between 2nd and 3rd molars. The palatine index showedthat, 66% were Leptostaphyline, 18% were Mesostaphyline and 16% were Brachystaphyline The palatine heightindex showed that 56% were Chamestaphyline, and 44% were Orthostaphyline.Conclusion: The present study identifies the commonest location of greater palatine foramen to be opposite the3rd maxillary molars which is useful for clinicians to perform procedures on palate. The morphometry is usefulin comparing the skulls of various origin.

Morphometric Study Of Pharyngeal Orifice Of Auditory Tube In South Indian Population

Auditory tube extends from the anterior wall of middle ear to the lateral wall of the nasopharynx at the level ofinferior turbinate. It plays an important role in maintaining the equilibrium of air. In the patients suffering fromchronic otitis media, the auditory tube plays an very important landmark for the endoscopic evaluation and fortransnasal approach to the infratemporal fossa. The present study was aimed to locate the pharyngeal orifice ofthe auditory tube in relation to the important anatomical landmarks. The study was carried out on 50 sagittalhead and neck sections of formalin fixed cadavers. The pharyngeal opening of auditory tube was looked for itsshape, size and position. The anatomical landmarks with reference to the pharyngeal opening of auditory tubetaken were posterior end of inferior turbinate, perpendicular distance from the clivus, from the roof of nasopharynx,from the posterior end of hard palate and from the anterior arch of atlas. The distance from these anatomicallandmarks to the pharyngeal orifice of auditory tube were measured using digital vernier calipers. The mean andstandard deviations of the distances were calculated and tabulated. The measured distances were slightlyhigher on the right than the left side. These differences were not statistically significant. The present study isuseful for otorhinolaryngologists to locate the position of pharyngeal opening of auditory tube endoscopicallyand evaluate patients with diseases of middle ear.

To determine effectiveness of abdominal hysterectomy versus non descent vaginal hysterectomy

Introduction: Hysterectomy is a very common surgery and can be performed by abdominal, vaginal or laparoscopic method though the abdominal route is more popular. Vaginal hysterectomy has distinct health and economic benefits. We designed this study to compare the outcomes in TAH and non-descent vaginal hysterectomy and to determine which route of hysterectomy is superior, safe and effective. Aims of the study: To determine the safety and effectiveness of abdominal hysterectomy versus non descent vaginal hysterectomy and to compare both in terms of duration of surgery, blood loss, intra operative complications, postoperative complications and duration of hospital stay. Materials and methods: This was a prospective, study done on total of 100 patients were divided randomly into two groups. One group underwent total abdominal hysterectomy and the other underwent vaginal hysterectomy. Both groups were compared for patient demographics, indications for surgery, size of uterus, duration of surgery, blood loss, need for blood transfusions, complications and duration of hospital stay. Results: Fibroid was the most common indication in both the groups. Most of the patients had 6 – 8 weeks size uterus. Mean intra operative blood loss in TAH group was slightly more than NDVH group. The need for blood transfusion was similar. The mean duration of surgery was 100.2 minutes in TAH group and 83 minutes in NDVH group. Fever was the most common complication in both groups. Abdominal wound infection and secondary suturing was seen in TAH group. The mean postoperative stay was 8.1 days in TAH group and 5.8 days in NDVH group. P. Divya Daniel, D. Anupama. To determine effectiveness of abdominal hysterectomy versus non descent vaginal hysterectomy. IAIM, 2017; 4(10): 77-86. Page 78 Conclusion: NDVH is associated with less duration of surgery, less blood loss, less postoperative stay than TAH. There was no difference between the need for blood transfusion between the two groups. Therefore, vaginal hysterectomy is safe and feasible in most of the women requiring hysterectomy for benign conditions and should therefore be attempted.
