Critical limb ischemia due to peripheral arterial occlusive disease is associated with a severely increased morbidity and mortality. There is no effective pharmacological therapy available. Injection of autologous bone marrow-derived mononuclear cells (BM-MNC) is a promising therapeutic option in patients with critical limb ischemia, but double-blind, randomized trials are lacking.

The following recommendations, which aim at standardising and rationalising the clinical indications for administering polyclonal immunoglobulins in Belgium, were drawn up by a working group of the Superior Health Council. To this end, the Superior Health Council organised an expert meeting devoted to"Guidelines for the use of immunoglobulins". The experts discussed the indications for immunoglobulin use, the'ideal'immunoglobulin preparation, its mechanisms of action, the practical issues involved in administering immunoglobulins and their potential side effects. The recommendations formulated by the experts were validated by the Superior Health Council working group with the purpose of harmonising immunoglobulin use in Belgium

OBJECTIVE: To compare oral administration of lomustine and prednisolone with oral administration of prednisolone alone as treatment for granulomatous meningoencephalomyelitis (GME) or necrotizing encephalitis (NE) in dogs. DESIGN: Retrospective cohort study. ANIMALS: 25 dogs with GME and 18 dogs with NE (diagnosis confirmed in 8 and 5 dogs, respectively). PROCEDURES: Records of dogs with GME or NE were reviewed for results of initial neurologic assessments and clinicopathologic findings, treatment, follow-up clinicopathologic findings (for lomustine-treated dogs), and survival time. Dogs with GME or NE treated with lomustine and prednisolone were assigned to groups 1 (n = 14) and 3 (10), respectively; those treated with prednisolone alone were assigned to groups 2 (11) and 4 (8), respectively. RESULTS: Prednisolone was administered orally every 12 hours to all dogs. In groups 1 and 3, mean lomustine dosage was 60.3 mg/m(2), PO, every 6 weeks. Median survival times in groups 1 through 4 were 457, 329, 323, and 91 days, respectively (no significant difference between groups 1 and 2 or between groups 3 and 4). Within the initial 12 months of treatment, median prednisolone dosage was reduced in all groups; dosage reduction in group 1 was significantly larger than that in group 2 at 6, 9, and 12 months. Combination treatment most frequently caused leukopenia, but had no significant effect on liver enzyme activities. CONCLUSIONS AND CLINICAL RELEVANCE: In dogs with GME and NE, oral administration of lomustine and prednisolone or prednisolone alone had similar efficacy. Inclusion of lomustine in the treatment regimen was generally tolerated well.

BACKGROUND: Delayed uterine involution has negative effects on the fertility of cows; use of prostaglandin F2alpha alone as a single treatment has not been shown to consistently improve fertility. Combined administration of PGF2alpha and PGE2 increased uterine pressure in healthy cows. We hypothesized, that the combination of both prostaglandins would accelerate uterine involution and have, therefore, a positive effect on fertility variables. In commercial dairy farming, the benefit of a single post partum combined prostaglandin treatment should be demonstrated. METHODS: 383 cows from commercial dairy farms were included in this study. Uterine size and secretion were evaluated at treatment 21-35 days post partum and 14 days later. Cows were randomly allocated to one of three treatment groups: PGF2alpha and PGE2, PGF2alpha or placebo. For every animal participating in the study, the following reproduction variables were recorded: Interval from calving to first insemination, days open, number of artificial inseminations (AI) to conception; subsequent treatment of uterus, subsequent treatment of ovaries. Plasma progesterone level at time of treatment was used as a covariable. For continuous measurements, analysis of variance was performed. Fisher's exact test for categorical non-ordered data and exact Kruskal-Wallis test for ordered data were used; pairwise group comparisons with Bonferroni adjustment of significance level were performed. RESULTS: There was no significant difference among treatment groups in uterine size. Furthermore, there was no significant difference among treatments concerning days open, number of AI, and subsequent treatment of uterus and ovaries. Days from calving to first insemination tended to be shorter for cows with low progesterone level given PGF2alpha and PGE2 in combination than for the placebo-group (P = 0.024). CONCLUSION: The results of this study indicate that the administration of PGF2alpha or a combination of PGF2alpha and PGE2 21 to 35 days post partum had no beneficial effect upon measured fertility variables. The exception was a tendency for a shorter interval from calving to first insemination after administration of the combination of PGF2alpha and PGE2, as compared to the placebo group. Further research should be done in herds with reduced fertility and/or an increased incidence of postpartum vaginal discharge.

OBJECTIVE: To investigate effects of isoflurane at approximately the minimum alveolar concentration (MAC) on the nociceptive withdrawal reflex (NWR) of the forelimb of ponies as a method for quantifying anesthetic potency. ANIMALS: 7 healthy adult Shetland ponies. PROCEDURE: Individual MAC (iMAC) for isoflurane was determined for each pony. Then, effects of isoflurane administered at 0.85, 0.95, and 1.05 iMAC on the NWR were assessed. At each concentration, the NWR threshold was defined electromyographically for the common digital extensor and deltoid muscles by stimulating the digital nerve; additional electrical stimulations (3, 5, 10, 20, 30, and 40 mA) were delivered, and the evoked activity was recorded and analyzed. After the end of anesthesia, the NWR threshold was assessed in standing ponies. RESULTS: Mean +/- SD MAC of isoflurane was 1.0 +/- 0.2%. The NWR thresholds for both muscles increased significantly in a concentration-dependent manner during anesthesia, whereas they decreased in awake ponies. Significantly higher thresholds were found for the deltoid muscle, compared with thresholds for the common digital extensor muscle, in anesthetized ponies. At each iMAC tested, amplitudes of the reflex responses from both muscles increased as stimulus intensities increased from 3 to 40 mA. A concentration-dependent depression of evoked reflexes with reduction in slopes of the stimulus-response functions was detected. CONCLUSIONS AND CLINICAL RELEVANCE: Anesthetic-induced changes in sensory-motor processing in ponies anesthetized with isoflurane at concentrations of approximately 1.0 MAC can be detected by assessment of NWR. This method will permit comparison of effects of inhaled anesthetics or anesthetic combinations on spinal processing in equids.

Objective-To evaluate local tissue compatibility of doxycycline hyclate (DOX) in antebrachiocarpal joints of calves. Animals-10 healthy calves between 80 and 110 kg. Procedures-Calves were assigned to 2 treatment groups. Calves in groups DOX(low) and DOX(high) were administered 5 and 10 mg of DOX, respectively, locally in 1 antebrachiocarpal joint. The contralateral joint served as a control joint and was injected with 0.9% NaCl solution. General and local clinical findings were scored. Several variables were assessed in blood and synovial fluid for 9 days. Calves were euthanatized and pathologic changes and drug residues evaluated. Results-Throughout the study, none of the calves had clinical changes or abnormal hematologic values. Significant differences between treatment and control joints were evident only for matrix metalloproteinases at 0.5 hours after injection, with less activity for the DOX-treated joints in both treatment groups. Values for all synovial fluid variables, except nitric oxide, increased significantly during the first 12 to 72 hours after arthrocentesis in control and DOX-treated joints. Histologic examination revealed minimal infiltration of inflammatory cells independent of the treatment. No drug residues were detected 9 days after arthrocentesis in any tissues obtained from the liver, kidneys, fat, and skeletal muscles. Conclusions and Clinical Relevance-DOX had excellent intra-articular compatibility in healthy calves. Arthrocentesis induced a mild transient increase of inflammatory mediators in the synovial fluid. Significant decreases in matrix metalloproteinase activity in DOX-treated joints may indicate a potential chondroprotective effect of DOX.

Whether and to what extent activation of peripheral presynaptic dopamine2-receptors may modulate the release of norepinephrine (NE) and so affect blood pressure (BP) in normal or hypertensive man is not clear. The hydrogenated ergotoxine derivative, co-dergocrine, given in effective antihypertensive rather than excessive experimental doses, has recently been shown to act predominantly as a peripheral dopamine2-receptor agonist in several species. Accordingly, BP regulation assessed has been in 8 normal men on placebo and after 3 weeks on codergocrine 4 mg/day. Co-dergocrine significantly reduced urinary NE excretion from 43 to 33 micrograms/24 h, supine and upright plasma NE 21 to 16 and 49 to 36 ng/dl, respectively, heart rate (-8 and -5%, respectively) and upright systolic BP, 115 to 102 mm Hg; upright diastolic BP also tended to be lower. A standard pressor dose of infused NE was lowered from 131 to 102 ng/kg/min, and the relationship between NE-induced changes in BP and concomitant NE infusion rate or plasma NE concentration was displaced to the left. Exchangeable sodium and plasma volume tended to be slightly decreased. Plasma and urinary electrolytes and epinephrine, plasma renin activity and aldosterone levels, pressor responsiveness to angiotensin II, the chronotropic responses to isoproterenol, and the NE-induced rise in BP, plasma clearance of NE, glomerular filtration rate and effective renal plasma flow were not consistently modified. The findings are consistent with effective peripheral dopamine2-receptor agonism by co-dergocrine in humans. Peripheral presynaptic dopaminergic activation may modulate sympathetic activity and BP in normal man.
