I~ Extensive Laceration in a Geld-ing. An eight-year-old Tennessee Walking Horse was admitted to Stange Memorial Clinic on July 23, 1953, with an extensive laceration on its left side. The wound began about eight inches behind the point of the shoulder and extended well back into its flank. It was about six inches deep just above the stifle and the wound gaped widely; there was also a small laceration on the point of the shoul-der. The course and damage may be seen in Figure 1. Sight was gone from the left eye, this presumably being a predisposing factor to the injury which occurred when the animal brushed against the top of a metal fence post. The top figure depicts the gelding on the day of arrival; the bottom, at the time of discharge. Upon arrival two days after the injury occurred, a guarded prognosis was given. This was based largely on the chance of a possible abdominal hernia, for the bowel could be seen moving in the deeply traumatized area. There was also danger that because of the extensive injuries to the muscles of the flank, loss of function would result to the left leg. The wound 40 could not be sutured since infection had gained entrance. The first week the area was kept covered with a drying wound powder (air slaked lime and boric acid powder, equal parts) and fly repellant was routinely ap-plied. For a short time it was found neces-sary to cleanse and irrigate the wound with potassium permanganate (1: 1000) before applying the powder because of the large accumulation of exudate. The animal began to improve and looked brighter and after the second week of this treatment, it was discontinued in favor of the original treatment. Much interest was shown by those ob-serving this animal and it was gratifying to see the rapid improvement that was being made. Daily examination disclosed the slowly but surely closing of the wound. Figure 2 shows the animal shortly before dismissal on October 9, at which time the animal showed no apparent lameness and further treatment seemed unnecessary. Roderick Zachary, '55 1 3 1 Coronary Thrombosis in a Dog. A thirteen and one-half-year-old Airedale Terrier was admitted to Stange Memorial Clinic on July 2, 1953. The his-tory revealed that the animal was con-stantly straining to defecate, drank ex-cessive amounts of water and had suffer-ed four heart attacks, the last being about a month previous. Further, the dog was unable to walk, had a fair appetite and had no vomitus during the preceding week. The initial examination, together with the history, suggested a myocardial in-volvement. Hence, an electrocardiogram was made and this was suggestive of an occluded coronary artery. The patient was then given an ampule (1.5 gr.) of Digifolin intramuscularly and placed in an oxygen tent. The following morning, July 3, a large amount of fluid feces was found in the cage. One ampule of Digifolin was again administered and the dog returned to the oxygen tent. In Iowa State College Veterinarian the evening another ampule of Digifolin was given. On July 4, the patient died. Post-mortem examination revealed a vavlular vegatative endocarditis involving the left atrio-ventricular valve, marked cardiac dilatation and a hemorrhagic in-farct in the lateral wall of the left ven-tricle measuring 3 cm. in diameter. Two emboli were present in the left coronary artery that supplied the infarcted portion of the myocardial wall. Multiple renal hemorrhagic infarcts were detected, and there was also a generalized chronic pas-sive hyperemia with a moderate amount of hepatic cirrhosis. Valvular defects and cardiac dilatation are not uncommon findings in old dogs, but coronary thrombosis has seldom been diagnosed in a living dog. Gary Kempers, '55 Cystic Calculus in a Pekingese. On Sept. 30, 1953, a three-year-old Pekingese female was admitted to Stange Memorial Clinic. She was emaciated, de-pressed and appeared toxic with a history of being sick periodically for the past two years. She had been treated several times for a kidney infection by a local veterinar-ian. Her owner noticed a hematuria along with frequent and scanty urination, and thought she could feel a stone in the ab-dominal area. Palpation of the abdomen revealed a large circumscribed mass in the region of the bladder; fluoroscopy dis-closed a cystic calculus. Because kidney infection was suspected, a blood urea de-terimination was made and found to be 172 mg. per 100 cc. of blood. Although the patient was a poor surgi-cal risk, a cystotomy was decided upon for the following morning. In the mean-time, the patient was given 200 cc. of dex-trose and B-complex solution and 70 cc. of parenamine subcutaneously. In addi-tion, 250 mg. of aueromycin was given orally. The latter was given to control in-fection in the bladder, but the patient vomited the medication a short time after administration. The patient was more de-Issue 1, 1953-54 Arrow points at the large cystic calculus. pressed in the afternoon and became comatose. During the evening prior to surgery, she died. The post-mortem findings revealed uremia as the cause of death. A cystic cal-culus, measuring approximately 7 x 8 cm., was found along with focal nephritis of the left kidney, a thickened bladder and an ulcerative hemorrhagic gastritis. While this case is not unusual in itself, it serves well to emphasize the necessity for a thorough examination of the patient: the cystic calculus was easily palpable and should not have been overlooked pre-viously. Jerry Shey, '54 Paratuberculosis in a Bovine. On Aug. 17, 1953, a three-year-old Shorthorn cow was admitted to Stange Memorial Clinic with a history of a chronic intestinal disorder. There had been other animals with the same symp-toms in the neighborhood, and a creek which ran through the pasture where this cow grazed also ran through several other neighboring pastures. Samples of blood, urine and feces were collected and tested. The blood and urine samples tested negative for any pathology. A few nematode ova and coccidial oocysts were found in the fecal sample. On August 20, a test was run using avian tuberculin. Six cubic centimeters of avian tuberculin was injected intra-venously at 9: 10 a.m. The results were as follows: 41
