A neutered female cat presented with a 9‐day history of hyporexia and depression. The referring veterinarian had identified moderate non‐regenerative anaemia, haematuria and suspected unilateral obstructive ureterolithiasis. Subsequent ultrasonography revealed moderate distension of the left renal pelvis with echogenic material, ureteral distension and ureterolithiasis. A partial ureteral obstruction was suspected. After 4 days of medical management, there was further distension of the renal pelvis with well‐delineated echogenic material and an accumulation of perinephric fluid. A left nephroureterectomy was performed. Renal pelvic rupture with intrapelvic haematoma and retroperitoneal haemorrhage was confirmed by histopathology. Eighteen months following surgery, the cat remained clinically well with normal renal values. [ABSTRACT FROM AUTHOR]

A lateral tibial head buttress plate designed for human beings was used to repair a highly comminuted tibial fracture in a two-year-old male labrador retriever caused by a gunshot wound. The plate was placed in a bridging fashion to provide minimal disruption of the fracture site and minimise surgical time. [ABSTRACT FROM AUTHOR]

There are 2 glucosyltransferases (GTF) produced by Streptococcus sobrinus C211, One enzyme, GTF-S, produces a water-soluble glucan that is a-1, 6-linked, with short, a-1, 3 branches, and the other enzyme, GTF-I, produces a water-insoluble glucan that is a-1, 3-linked with a-1, 6 branches. Hydrogen peroxide was found not only to be a potent inhibitor of GTF activity, but also a stimulator of GTF activity when employed are relatively low concentrations. At 0.88 M, H2O2 completely inhibited insoluble glucan synthesis, whereas at a 0.29 M concentration, H2O2 enhanced synthesis of the same glucan. Soluble glucan synthesis was also inhibited by H2O2 at 1.47 M. Low concentrations of hydrogen peroxide with GTF-S, however, caused the enzyme to convert from soluble glucan production to insoluble glucan production. 13C-Nuclear magnetic resonance spectra of glucans produced by peroxide-treated GTF confirmed that the production of a-1, 3 linked glucans was increased with H2O2-treated GTF-S.

Emotional behavior and activity levels were studied following administration of ethanol and/or a carbamate pesticide, methomyl, to rats via a ground chow diet. Acetylcholinesterase levels were lowered following the experimental diets. The group having the greatest reduction in AChE, the methomyl group, showed less evidence for habituation in an open-field test. No differences relative to control subjects were noted on handling and muricide tests.
