Para tanto, as gatas foram divididas em cinco grupos (n=10) e de forma aleatória os animais foram tratados com 1 ml de Arnica 30DH SC (GA30SC); Arnica 30 DH VO (VO) (GA30VO); Arnica 6 DH VO (GA6VO); 2mg/kg de cetoprofeno SC (GC) na primeira aplicação, e 1mg/Kg nas restantes ou 0,1mg/kg de morfina SC (GM). Após 30 minutos realizou-se a OSH e os animais foram avaliados quanto à sedação e dor pós-operatória, por meio de EAV, ECV e hiperalgesia, pelo limiar mecânico nociceptivo por meio dos monofilamentos de Von Frey. Quando o escore da ECV e EAVID atingiram 33% do valor máximo foi realizado o resgate analgésico administrando-se 0,3 mg/kg de morfina IM. Além das escalas anteriormente citadas também foi observado a ocorrência de emese, defecação, micção, peso e cicatrização. Com exceção dos animais tratados com morfina, não houve incidência de vômito. Não houve diferença significativa entre os grupos na defecação, micção, peso e cicatrização. A hiperalgesia foi observada apenas nos momentos em que a EAVID e ECV ultrapassaram 33%, isto é nos momentos em que foi realizado o resgate analgésico. O cetoprofeno e a morfina foram mais eficazes que a Arnica, não houve diferença entre as dinamizações 6DH e 30DH VO, nem entre as vias SC e oral de administração da Arnica em gatas submetidas à OSH / The analgesic effect of Arnica was compared to ketoprofen in 50 cats undergoing ovariosalpingohysterectomy (OSH). Cats were randomly divided into five groups of same number (n=10). The animals were treated with 1 ml of Arnica montana 30DH subcutaneously (SC) (GA30SC); Arnica montana 30 DH orally (GA30VO); Arnica montana 6 DH orally (GA6VO); 2 mg/kg of ketoprofen SC (GC) or 0.1 mg/kg of morphine SC (GM). Surgery was performed 30 minutes after treatments and the animals were evaluated for sedation and postoperative pain through visual analogue scale (VAS), variable count scale (VCS) and hyperalgesia, measuring the mechanical nociceptive threshold by von Frey monofilaments. When VAS and VCS score reached 33% of the of the maximum, analgesic rescue was performed by administering 0.3 mg/kg of morphine intramuscularly. Occurrence of vomiting, stools, urine output, weight and healing was evaluated in addition to the aforementioned scales. Except for the animals treated with morphine, there was no vomiting. There was no significant difference between groups in the stools, urine output, weight and healing. The hyperalgesia was observed only when the VCS exceeded 33% of the total score, when animals received rescue analgesia, but there were no differences between groups. Ketoprofen and morphine were more effective than Arnica montana for postoperative analgesia in cats undergoing ovariohysterectomy. There was no difference between oral Arnica montana at 6DH and 30DH or subcutaneous and oral administration of Arnica montana in cats undergoing ovariohysterectomy

M.Tech. / The homoeopathic medicine Arnica montana is often prescribed in cases of trauma, before and after surgery and in cases where there is bleeding. Many conventional medical practitioners, however, do not advise its use for the above complaints due to the herbally prepared Arnica montana mother tincture containing coumarin derivatives which are said to have an anti-coagulant effect and cause a potential risk of bleeding. The aim of this particular study was to investigate the in vivo effect of the complex remedy Arnica montana composing of potencies 6C, 30C and 200C on coagulation and bleeding. This study forms part of a three part in vivo study to determine the effect of homoeopathic Arnica montana in various potencies on blood coagulation. The effect of Arnica montana on blood coagulation was evaluated by measuring the Bleeding Time (BT), activated Partial Thromboplastin Time (aPTT) and Prothrombin Time (PT). This is a double blind, placebo controlled trial with a total sample group of eighty healthy participants between the ages of eighteen to thirty five. As this study forms part of a three part study the total sample group was shared. Twenty participants were allocated to the placebo group and received 20% ethanol. Twenty participants were allocated to the experimental group and received the complex homoeopathic preparation of Arnica montana 6C, 30C and 200C in 20% ethanol. The Bleeding Time was measured by a trained medical technologist and blood samples underwent coagulation tests comprising of aPTT and PT. The study was conducted over a period of two weeks at the UJ Doornfontein Campus Homoeopathy Health Centre. After two weeks another venous sample was drawn by the phlebotomist and sent away for the same coagulation studies as described above. The technologist again measured the Bleeding Time. Results obtained from the Prothrombin Time, activated Partial Thromboplastin Time and Bleeding Time tests pre- and post medication were compared and v analysed. Analysis of data was done using SPSS 15.0 (Statistical Package for Social Sciences). Results showed that complex remedy Arnica montana 6C, 30C and 200C had no significant effect on blood coagulation and bleeding in vivo.

The tectonic region that encompasses Southwestern Montana is a petrologically complex area containing several batholiths and thrust faults, underlined by Precambrian basement rock and capped by sedimentary rocks. Intrusive volcanism of Southwest Montana best represented by the Pioneer and Boulder batholiths is a product of the eastward subduction of the Farallon Plate underneath the North American Plate during the Mesozoic time. Geochemical modeling made evident that the Pioneer and Boulder batholiths have a comagmatic relationship. This conclusion is derived from variation, spider and REE diagrams along with petrographic and geochemical models. The intrusion of these batholiths is likely related to the emplacement of a detached portion of the Idaho batholith known as the Sapphire block. Future models that are outside of the scope of this research must consider the evidence proposed in this document to produce an overarching model for the intrusion of the Pioneer and Boulder batholiths in the incredibly dynamic tectonic setting of the Mesozoic.

Cougars (Puma concolor) are elusive top-level predators and their predation patterns, particularly upon sensitive species, can be a source of concern to wildlife managers. Predation patterns, however, vary widely in accordance with differing landscape attributes, prey community composition, and preferences of individual cougars. The objective of this study was to better understand the impact of cougars upon their prey in the Pryor Mountains of Wyoming and Montana. Managers were concerned that cougar predation was having a negative impact upon a small, isolated Rocky Mountain bighorn sheep (Ovis canadensis canadensis) population and were hoping predation might be limiting a burgeoning feral horse population (Equus caballus). With GPS collar data, we examined cougar kills (n = 200) to determine kill rates, prey composition, and selection for prey. Our findings indicated this population of cougars preyed primarily on mule deer (Odocoileus hemionus; 71.5%) but also included a substantial amount of bighorn sheep (8.0%) and other prey items (19.5%) in their diet. All bighorn kills were attributable to a specialist individual and we found no evidence of predation upon feral horses. Results showed that, while cougar predation was not limiting the feral horse population, at times, predation could be one of a host of factors limiting the bighorn sheep population. To better understand the link between the risk of cougar predation and landscape attributes, we examined predation-specific resource selection by cougars. We first compared our set of confirmed kill sites to random sites at a fine scale (within 25 m of kill sites). We then built resource selection functions to conduct a coarse-scale analysis by using the 95% upper cut-off point of the known distances-dragged (94.9 m) to buffer caches sites, thereby creating zones of risk which had high probabilities of containing kill sites. We found that risk of cougar predation was associated with vegetation class and increased with decreasing horizontal visibility. For bighorn sheep, risk of predation was associated with juniper-mountain mahogany (Juniperus spp., Cercocarpus ledifolius) woodlands. We recommend managers thin junipers to increase horizontal visibility in areas where the juniper-mountain mahogany vegetation class intersects bighorn sheep habitat.

The purpose of this study is to characterize the metasomatism that has taken place as a result of the chemical incompatibility between mafic and metaultramafic bulk compositions during high-grade regional metamorphism in the Tobacco Root Mountains, southwest Montana. Metasomatism of these rocks took place by both diffusionand infiltration-dominated processes. The result of these processes are characterized mineralogically and geochemically in the rocks.
