In vivo thrombolysis. An experimental model in rhesus monkeys

An experimental model of diffuse thromboembolism in the intrarenal circulation of the rhesus monkey was produced by intra-arterial injection of homogenised, homologous [125-I]fibrin. A sequential study of thromolysis was carried out using the conventional method of determining the thromboembolic index in the arteries of both kidneys together with radioautography and counting of radioactivity in the renal homogenate. Quantitative estimation of radioactivity in the renal homogenate, as well as radioautography of kidney sections provided more accurate and sensititve indices of the thrombolytic process than the conventional thrombembolic index. Studies on blood coagulation and fibrinolysis revealed only mild changes corresponding to the dynamics of thrombolysis in vivo. It was further noted that the thrombolytic mechanism in rhesus monkeys is very active and can clear thromboemboli from the intrarenal arteries within 8 days of their induction

Identification of sex from tarsal bones

Bone weight as a discriminative factor for identification of sex was studied in tarsal bones (172 calcanei and 164 tali) from the Varanasi region. The DPs for the weight of these bones identified sex correctly in a good percentage of cases, especially from the male bones. The findings suggest weight of tarsal bones as a useful metrical feature for discriminating sexual dimorphism.

Transposition of the great arteries. A review of 37 cases after Mustard's operation

Ihenacho, H. N. C., Patel, R. G., Singh, S. P., Astley, R., and Parsons, C. G. (1973).Thorax, 28, 448-452. Transposition of the great arteries. A review of 37 cases after Mustard's operation. Thirty-seven children with transposition of the great arteries have undergone Mustard's operation in Birmingham Children's Hospital from May 1968 to December 1971. Thirtythree of these had simple transposition of the great arteries and four were complicated. All but two had some previous palliative procedures. Ten patients died before discharge from hospital and there were two late deaths, one after three months and the other after eight months. Bleeding, dysrhythmia, and hypotension were common immediate postoperative complications, while recurrent heart failure and persistent atrioventricular block occurred in five and four patients respectively.

The lack of value of hepato-jugular reflux as a sign of heart failure

An investigation was carried out of the diagnostic value of hepato-jugular reflux in patients with heart failure.

The effect of abdominal compression on superior vena cava pressure was assessed in patients with and without heart failure. In four of the six patients without congestive cardiac failure, during compression, whether applied in the right hypochondrium or left iliac fossa, there was a significant rise in vena cava pressure. A similar response was also observed in three patients with congestive heart failure.

Hepato-jugular reflex is not a reliable sign of incipient heart failure.

Heart failure and neonatal hypocalcaemia

Six infants had congestive heart failure for which no cause could be found apart from a low serum calcium. All except one recovered completely and had normal chest x-ray appearances and E.C.G.s on discharge from hospital. Necropsy on the infant who died shoed engorgement and dilation of the right side of the heart and a small ductus but no other abnormalities. It is suggested that hypocalcaemia should be considered as a possible cause of heart failure in infants, especially when oedema is prominent.
