Relationship between the preoptico hypophysial system and the vascular system in the teleost Rita rita (Ham.)
(Springer-Verlag, 1975) A.G. Sathyanesan; Radha C. Das
In Rita rita the internal carotid artery gives rise to hypothalamic and hypophysial arteries. The hypophysial artery directly enters the pituitary and largely contributes to the interface vasculature lying in between the neurohypophysis and the pars distalis which can be considered as an equivalent of the median eminence. Blood vessels from the interface vasculature enter the pars distalis. The hypothalamic artery gives rise to the primary capillary plexus in the infundibular floor and the portal vessels formed by it irrigate the glandular pituitary. Both, at the level of the hypothalamus and at the interface, neurosecretory material might get access to blood vessels. Thus, in Rita rita, not only the typical teleostean type of hypothalamo-hypophysial vascularization is present, but also an incipient tetrapodal pattern is evident. © 1975 Springer-Verlag.
Influence of experimental dietary conditions on hepatic enzymes of glutamic acid metabolism in rats
(1975) Harbans Lal; K.N. Agarwal
The lowering levels of dietary protein induced a significant fall of some hepatic enzymes associated with glutamic acid metabolism. The changes were later normalised during dietary rehabilitation of the protein-deprived rats. The levels of these enzymes were found to be increased as compared to those observed after starvation, on feeding a carbohydrate-free, protein-rich diet or by the dietary supplementation by glutamic acid. © 1975 S.

Complexes of titanium and zirconium tetrahalides with isonicotinic acid hydrazide and its acetyl and benzoyl derivatives
(1975) R.C. Aggarwal; Thakur Prasad; B.N. Yadav
The reactions of titanium and ziroconium tetrahalides with isonicotinic acid hydrazide (INH), acetyl isonicotinic acid hydrazide (AINH), and benzoyl isonicotinic acid hydrazide (BINH) have been carried out under anhydrous conditions. The complexes MF4·INH, 2MF4·AINH, 2MF4·BINH, TiCl2(INHH)2, ZrCl3(INH:H)·2THF, ZrCl3(INHH), MCl2(AINH-2H) and MCl2(BINH-2H), (where M=Ti or Zr) have been isolated and their i.r. spectra in 4000-200 cm-1 region studied. © 1975.
On the Electrodeposition of Copper Alloy Powders from Baths Containing Citrate/Tartrate Additives
(1975) R.K. Dube; P.M. Prasad
The cathode polarization behavior of copper, zinc, cadmium, and tin in complex baths containing sodium citrate/sodium tartrate additives was investigated. Copper exhibited considerable polarization in baths containing sodium citrate or sodium tartrate. The polarization behavior of zinc, cadmium, and tin was not significantly affected by these additives. Codeposition of zinc, cadmium, or tin with copper was not possible from baths containing no complexing agents. However, studies on the cathode polarization characteristics from baths containing 40 g/liter sodium citrate/sodium tartrate and actual deposition trials revealed that whereas Cu-Sn powder can be codeposited, it was not possible to codeposit Cu-Zn or Cu-Cd powders. © 1975, The Electrochemical Society, Inc.

Sodium fluoride induced changes in the hypothalamic neurosecretory system of the spotted owlet, Athene brama Temminck
(1975) K.B. Singh; C.J. Dominic
Administration of 10 or 20 mg of sodium fluoride (NaF) induced depletion of neurosecretory material (NSM) from the neurons of the supraoptic (SON) and paraventricular (PVN) nuclei in spotted owlet (Athene brama Temminck). The residual NSM in the perikarya was arranged in cap like paranuclear positions. The NSM in the hypothalamo hypophysial tract, the zona externa of the anterior median eminence (ME) and in the neural lobe (NL) showed only a partial loss. The effects of NaF administration on the HNS of the spotted owlet are similar to those induced by such stimulators of ADH secretion as hypertonic saline, morphine and formalin. Hence the histological changes induced by NaF administration in the HNS of the spotted owlet are presumably indicative of increased neurosecretory activity resulting in the augmented secretion of ADH. It is suggested that NaF, like other stressful agents, is a stimulator of ADH secretion.

Effect of herbicides on the carbohydrate and nitrogen contents of nutgrass (Cyperus rotundus L.)
(1975) L.P. Misra; L.D. Kapoor; R.S. Choudhri
The effect of four herbicides on the starch and nitrogen contents of the tubers, dry matter production, carbohydrate, amide, amino, ammonium and nitrate nitrogen contents of the foliage of nutgrass (Cyperus rotundus L.) under pot culture conditions was studied. The starch content of the tubers of nutgrass depleted maximum by the Embutox-plus and Tok E-25 when applied as foliar spray and soil placement, respectively. The foliar application of Embutox-plus and Tok E-25 appeared to have maximum reduction in the carbohydrate and different nitrogen contents in the foliage of nutgrass as compared with other herbicides used. Severe reduction in the amide and amino nitrogen was observed as against ammonium or nitrate nitrogen content on the application of herbicides. © 1975 Indian Academy of Sciences.
Structure of the neurohypophysis and the hypothalamo hypophysial vascularization in the teleost Channa punctatus Bloch
(1975) A.G. Sathyanesan; T.M. Jose
In C. punctatus the median eminence includes the subterminal region of the hypothalamus and the anterior neurohypophysis. It is formed of ependymal, fibrous and reticular layers as in the tetrapods. Primary capillary plexus extends from the subterminal region to the extremity of the anterior neurohypophysis. Only a few portal vessels from the hypothalamus enter in the pars distalis. All the components of pituitary including the pars intermedia are irrigated by the secondary plexus formed from the portal vessels emerging out of the anterior neurohypophysis. The neurosecretory axons and the ependymal cells are in close morphological contact with the primary plexus. Several axons have perivascular endings at the median eminence. Some axons were found to be only silver or aldehyde fuchsin positive whereas some others had taken up both. The silver positive axons were abundant in the pars distalis and the AF positive ones were more concentrated in the pars intermedia with greater accumulation of neurosecretory material.

Management of old unreduced traumatic dislocations of the hip. A study of twenty nine cases
(1975) B.P. Varma
Twenty nine cases of neglected traumatic dislocations of the hip seen after an interval of 14 days to 6 years from the date of injury have been studied over a period of 5 years. There were 18 children and 11 adults. The cases were treated by closed reduction, open reduction, corrective trochanteric osteotomy and resection of the head and neck of the femur. Minimum follow up was 3 months and maximum 12 months, average 5.1 months. An initial period of traction followed by manipulation under general anaesthesia succeeded in achieving reduction in 4 cases. Operative reduction was performed after a period of traction in 21 cases. The results were comparatively better in adults, 85.7 percent showed excellent results in contrast to 57.1 percent excellent or good results amongst children. In the limited follow up only one case showed flattening of the capital epiphysis. Anterior approach to the hip was found useful as it permitted mobilisation of the contracted soft tissues in the anterior aspect of the joint.
Results of treatment of spinal tuberculosis by 'middle path' regime
(1975) S.M. Tuli
The efficacy of modern drugs in the treatment of tuberculosis of the spine was evaluated by a follow up for 3 to 10 yr of 900 cases. Operation on the vertebral lesion was done only for those patients with or without neural complications who failed to respond favourably to drug therapy and rest. Thus absolute indications for operation were present in only 6% of cases without neural involvement and in 60% of patients with neural deficit. Of the patients who responded to drug therapy alone, only 19% revealed increase of kyphosis by more than 10 degrees. The diseases area showed radiological evidence of osseous replacement in 29.6% of cases, of fibro osseous union in 50% and of fibrous replacement in 20.2%. The overall results of this regime compare favourably with those of radical operation. It is suggested diseased treatment should in the first place be by modern antitubercular drugs.
PATHOGENESIS OF STAPHYLOCOCCAL INFECTIONS OF THE SKIN
(1975) GURMOHAN SINGH
Staphylococcus aureus does not grow readily on normal skin, where an important factor inhibiting its growth is the resident flora. Hydration of the stratum corneum favors the growth of S. aureus. Before lesions of staphyloderma are produced, organisms multiply on the surface. Substances produced as the result of multiplication enter the skin and produce an irritant reaction characterized by necrobiosis, spongiosis followed by perivascular infiltration, exocytosis and intraepidermal vesicle formation. A technique was used whereby the skin surface was separated from growing S. aureus by a filter. Pustules were produced through the filter. Copyright © 1975, Wiley Blackwell. All rights reserved
Peritonsillolith
(1975) H.C. Samant; O.P. Gupta
Peritonsillolith appears to be an unknown entity. Two cases of lithiasis in the peritonsillar region following spontaneous rupture of peritonsillar abscesses have been reported. The authors have speculated concerning the cause of stone formation in the peritonsillar region, which has been designated "peritonsillolith," on the basis of lithiasis in other regions of the body, such as gallbladder, kidneys, and salivary glands. Peritonsilloliths most likely form as a result of incomplete evacuation of pus, the dead bacteria and the pus cells providing the nidus for their formation. The salts of these stones are undoubtedly derived from the inflammatory exudates and saliva. © 1975.
Cyclophosphamide induced dysmelia in chick embryos
(1975) S. Singh; G.V. Lakshmy; P.K. Gupta
Three hundred and ninety four chick embryos collected on 15th to 19th day of incubation, after cyclophosphamide injection into their yolk sacs on 3rd to 6th day of incubation, showed dysmelia in 55 per cent of cases. Eighty two per cent of the affected limbs showed bilateral involvement. Besides other anomalies, the malformations of the limbs included micromelia, rotational deformities, and various digital defects, the latter being the most frequent. Of the digital anomalies, brachydactyly was the commonest (46 per cent) as compared to ectrodactyly (7 per cent) and syndactyly (2 per cent). Individually, the second toe showed the highest incidence of brachydactyly (41 per cent). Preferential attack of cyclophosphamide on 2nd toe and its suppressive effect especially on the mesenchyme possibly disturbing the interaction between the mesoderm and its overlying ectodermal ridge, are discussed.
