We report the first case of bovine tuberculosis in a free-living Iberian lynx (Lynx pardina), an extremely endangered feline, from Doñana National Park in Spain. The isolate (Mycobacterium bovis) correlates by molecular characterization with other isolates from wild ungulates in the park, strongly suggesting an epidemiologic link. Mycobacterium bovis infects many animal species, with wild and free-ranging domestic ungulates being the main reservoirs in nature (1).

Three anesthetic protocols, each using an alpha-2 agonist sedative in combination with a dissociative anesthetic, were evaluated in 17 captive fallow deer (Cervus dama). The alpha-2 agonist was given first in two of the three protocols: 1) detomidine (0.1-0.2 mg/kg i.m.) followed by tiletamine-zolazepam (3.0-6.3 mg/kg i.m.) and 2) xylazine (0.6-0.9 mg/kg i.m.) followed by tiletamine-zolazepam (4-5 mg/kg i.m.). In the third protocol, xylazine (1.0-6.2 mg/kg i.m.) and ketamine (2.5-5.1 mg/kg i.m.) were given simultaneously. Each of the sedative/anesthetic combinations produced acceptable immobilization in fallow deer and both provide an alternative to narcotic anesthesia.

The evaluation described in this article compared the Therevac SB "mini-enema" with bisacodyl suppositories in the bowel management programs of patients with spinal cord injury (SCI). Of particular interest were (a) determining whether the additional costs of Therevac SB could be justified and (b) identifying the degree of bowel program improvement possible. Fourteen SCI patients were selected from the SCI inpatient unit and the clinic of a Department of Veterans Affairs facility. All patients experienced a delay of at least 45 minutes between insertion of a suppository and the beginning of stool evacuation. Each patient used bisacodyl suppositories for five bowel programs, then Therevac SB for five programs, finally repeating the bisacodyl suppositories for five more programs. Each patient maintained a bowel program log. Ten patients completed the evaluation. Using a MANOVA, the authors found a significant difference between bisacodyl and Therevac SB mean evacuation times for this group. An analysis of direct and indirect costs related to bowel care with the two regimens is also presented.

A back injury prevention program was developed for the Spinal Cord Injury (SCI) nursing staff at the San Diego Veterans Affairs Medical Center (SDVAMC). This preventive program has the following components: 1. All nursing staff are sent to a one hour "back school" in order to learn and practice proper body mechanics. This program is held in the therapy clinic and conducted by a kinesiotherapist. In addition, each nurse must be certified in transfer techniques by our clinical nurse specialist, before performing transfers on patients. 2. All nursing staff participate in 5-10 minutes of stretching, warm-up exercises at the beginning of their shift. These exercises are helpful as injuries are less likely to occur when muscles have been warmed up prior to lifting and moving patients. 3. All nursing staff wear a lumbar sacral back support while on duty. This device will offer physical support to the lower back as well as provide a mental reminder to use proper body mechanics when transferring patients. This back injury prevention program has been in effect since the opening of the SCI unit in March 1989. The rate of low-back injuries on the SCI unit from October 1989 to September 1990 was compared to the rate of low-back injuries on the other hospital units. As a result of this program, there were only four low-back injuries with six lost work days on the SCI unit. This rate compares favorably with the incidence of low-back injuries in other patient care areas.

Four methods of fistulorrhaphy used by us in 96 cases of vesicovaginal fistulas after hysterectomy are described. Obtained results are presented.

Different methods of urinary derivation are described, which are performed in gynecologic patients. Operative technics, their advantages and disadvantages and plans for selection of derivative methods are discussed.

Acid phosphatase (othophosphoric monoester phosphohydrolase (acid optimum), EC 3.1.3.2) from the human prostate was immobilized by its protein moiety on cyanogen bromide-activated Sepharose, by carbohydrate moiety on Concanavalin-A-Sepharose, and by Schiff base formation with partially oxidized carbohydrate groups on ethylenediamine-Sepharose. The highest retention of enzyme activity, 80%, was found for the noncovalent immobilization on Concanavalin-A-Sepharose. It was demonstrated that the optimal pH changes for the Concanavalin-A-Sepharose and CNBr-Sepharose-enzyme complexes are electrostratic in character. In all cases of immobilization the enzyme has higher thermostability than that for the native enzyme under the same conditions. The effects of the enzyme stabilization were interpreted in terms of the multipoint interaction between the enzyme molecule and the carrier.

The operative repair of retroglandular hypospadias should be individualized. In some cases only resection of hooded foreskin and meatotomy are required. In a small number of properly selected cases a one-stage operation may be performed. In most cases a three-stage repair was carried out by the authors.

Soluble alkaline phosphatase from Thiobacillus thioparus cells was purified about 230-fold. The enzyme had a mol. wt. of 50 000 daltons, optimum pH at 10.5, and was heat-resistant in the presence of diethanolamine. Polyacrylamide-gel electrophoresis demonstrated contamination of the preparation with inactive proteins and the presence of two active bands. The enzyme activity was distinctly stimulated by increasing concentrations of Tris or diethanolamine. In the presence of glycine, 1 mM-Zn2+ enhanced the enzyme activity; in Tris or diethanolamine buffers the activity was stimulated by 1 mM-Mg2+ whereas Zn2+ had a strong inhibitory effect. Glycine at concentrations exceeding 25 mM also inhibited the enzyme. Specificity of the enzyme is fairly broad.
