A subacute oral toxicity study of 6-amidino-2-naphthyl 4-[(4,5-dihydro-1H-imidazol-2-yl) amino] benzoate dimethanesulfonate (FUT-187), a new protease-inhibiting agent, was carried out in beagle dogs of both sexes. FUT-187 was administered to dogs at daily oral doses of 15, 50 and 150 mg/kg. Dogs in 150 mg/kg group were given twice a day in a.m. and p.m.. The results were as follows: 1. Changes of physical sign attributed to FUT-187, consisted of vomiting, diarrhea, salivation, decrease of locomotor activity, sedation and hyperemia of eye mucosa. These changes expect vomiting vanished within about 2 hours after treatment. One male given 150 mg/kg died on day 19 and two females given 150 mg/kg were sacrificed on day 55 and 67 due to deterioration of systemic conditions. 2. Body weight gain was suppressed in males given 150 mg/kg and females given 50 mg/kg or more. 3. In hematological examinations, some changes suggesting anemia or inflammation were observed in a few animals received 50 mg/kg or more 4. In serum biochemical examinations, dogs given 50 mg/kg or more had decrease of albumin, total protein, A/G ratio and total cholesterol, increase of GPT activity. In liver function test, decrease of function was observed in a few animals in 150 mg/kg group. These changes diminished by the end of recovery period. 5. In autopsy findings, ulcer formation and desquamation of mucosa in the digestive tract were observed in dead or sacrificed animals and survived animals given more than 50 mg/kg. In sacrificed animals, liver was yellow in color and intussusception was seen. 6. Plasma levels of intact FUT-187 and metabolites on the day 37 or 83 were higher than that on the first day of administration. 7. In histopathological examinations, ulcer formation, desquamation, degeneration and/or atrophy of mucosa in the digestive tract were observed in the animals from 50 mg/kg and 150 mg/kg groups. In addition, fatty deposition in hepatocytes was observed in one dead animal and two sacrificed animals.(ABSTRACT TRUNCATED AT 400 WORDS)

A 2-yr-old female red wolf (Canis rufus gregoryi) presented with weight loss and diarrhea. Abnormal clinical pathology included low serum calcium, sodium, chloride, globulin, and albumin levels. Differential diagnosis included infectious enteritis, intestinal parasitism, inflammatory bowel disease, hepatic or renal disease, and malnutrition. The wolf was treated empirically, but did not improve. A second examination revealed persistent poor musculature and stool quality. Abdominal palpation revealed a firm mass; contrast radiography confirmed an intussusception. Exploratory laparotomy revealed a colocolic intussusception involving the cecum. Following reduction of the colocolic intussusception, cecal inversion (cecocolic intussusception) was identified. Because the cecal inversion could not be reduced, typhlectomy was performed through a colotomy incision. Bacterial culture of peritoneal fluid yielded two strains of Escherichia coli. Postoperatively, the wolf was placed on antibiotics and a soft diet. The diet was gradually returned to its normal formulation and the wolf progressively gained weight. Physical examination 7.5 mo following initial presentation revealed normal body weight and condition. To our knowledge, this is the first recorded incidence of cecal inversion with concurrent colocolic intussusception.

Hypovolemia is the most common cause of circulatory failure in children and may lead to critical tissue perfusion and eventually multiple-organ failure. Administration of fluids to maintain or restore intravascular volume represents a common intervention after hemorrhagic shock occurring during surgical procedures or in patients with trauma. Notwithstanding, there is uncertainty whether the type of fluid may significantly influence the outcome, especially in pediatrics. Both human albumin and crystalloids are usually administered: the advantages of crystalloids include low cost, lack of effect on coagulation, no risk of anaphylactic reaction or transmission of infectious agents. However, large amount of crystalloid infusion has been correlated with pulmonary oedema, bilateral pleural effusions, intestinal intussusception, excessive bowel edema, impairing closure of surgical wounds and peripheral edema. Moreover, intravascular volume expansion obtained by crystalloids is known to be significantly shorter and less efficacious than colloids. Among synthetic colloids, gelatins have been used for many years in children, also in early infancy, to treat intravascular fluid deficits. Hydroxyethylstarch (HES) preparations have been introduced recently, becoming very popular for vascular loading both in adults and children. However, the number of pediatric studies aimed at evaluating HES efficacy and tolerance is limited. Given the ongoing controversies on the use of colloids in childhood, this review will focus on the pharmacodynamics of synthetic and non synthetic colloids for the treatment of critical blood loss in pediatrics.
