Abstract
Eliminating dog-mediated human rabies cases by 2030 is a collective global pledge. Rabies is a vaccine-preventable, zoonotic, and fatal viral disease tormenting human beings and animals for at least four thousand years. An average annual fatality of 59,000 people has been reported from rabies in more than 150 countries, including Nepal. Understanding people's knowledge towards rabies is paramount to preventing this disease. A cross-sectional study was conducted in three districts, namely, Siraha, Parsa, and Parasi in Nepal, from October to December 2021 to assess the level of public awareness of rabies. Information was obtained using a structured questionnaire among 308 household heads. Study findings show that some of the respondents were unfamiliar with the term 'rabies'. They knew major carriers or sources of rabies, but the majority of them (87.3%) did not know its causative agent. They had some idea of how rabies is transmitted from animals to humans, but they lacked a clear understanding of the fate of the animals and humans once affected cases are symptomatic. Only 35.1% of respondents knew that rabies pathogens attack and multiply in the brain tissues. Rabies vaccination in pets is critical for rabies eradication, yet only 26.3% of respondents were aware of the vaccination schedule. Nearly 90% of respondents thought post-exposure prophylaxis (PEP) to be effective immediately after a suspected animal bite. The findings show that there was a significant relationship between independent variables viz. pet ownership (X2 = 20.273, p < 0.001), level of education (X2 = 39.215, p < 0.001), household income (X2 = 13.574, p < 0.001), family size (X2 = 15.053, p < 0.001), main occupation (X2 = 11.618, p = 0.020), age (X2 = 6.982, p = 0.008) with dependent variable i. e., knowledge category (good and poor knowledge). Education to invoke awareness among rural people about rabies, its transmission and prevention, including making anti-rabies vaccines freely available, should be the priority for municipalities, public health and veterinary health authorities in the study districts and throughout the country.

Abstract
Rabies is a vaccine-preventable, zoonotic, viral disease and a major public health concern for developing countries such as Nepal. A study was conducted from October-December 2021 among 308 household heads from three districts in Nepal (Siraha, Parsa, and Nawalparasi West) through an in-person interview to examine the rural people's practices towards rabies. Of 70 respondents owning pet animals, 82.9% vaccinated them against rabies but 87.9% (51/58) of them kept a vaccination record. Nearly all respondents (99.7%, 307/308) said they would visit hospitals after being bitten by rabid or rabies suspected animals, and 18.2% (56/308) of them said they would also opt to visit traditional healers seeking treatment against rabies. Seven in ten respondents knew that they should wash bitten body area with soap and water. Around 60% (184/308) of respondents said they would not bother to notify or report to the local authorities if they saw someone bitten by a presumed rabid dog or observed animal behavior suggestive of rabies. The Chi-square test showed a significant association between the socio-demographic characteristics of respondents with practices (good practice and poor practice) towards rabies. The study findings suggest that rural people in Nepal need to be educated with applied rabies control and prevention practices and made aware of health seeking behavior and the role that a community members have to play to control, prevent, and eradicate rabies.

Abstract
BACKGROUND Nematodes of the genus Dirofilaria are widespread vector-borne helminths (VBH) of veterinary relevance. Dirofilariosis caused by D. immitis is frequently diagnosed in dogs often showing a severe clinical condition known as heartworm disease. Assessing the distribution pattern of canine dirofilariosis is pivotal to undertake appropriate control measures and define the risk of infection in animals and humans. This study provides original data on the occurrence of D. immitis in naive stray dogs from Nepal. METHODS An epidemiological study was performed on stray dogs from Siddharthanagar, Lumbini region, Nepal. Alive animals were blood sampled and examined for microfilariae using direct microscopy, buffy coat centrifugation and modified Knott's method. In addition, hematobiochemical parameters, including packed cell volume (PCV), alanine aminotransferase (SGPT), aspartate aminotransferase (SGOT), alkaline phosphate (ALP), creatinine, blood urea nitrogen (BUN), urea and total protein were analysed, along with a clinical scoring (body temperature and respiratory rate). During the observation period, data on autopsies performed on stray dogs showing canine heartworm disease were also included. RESULTS The overall prevalence of D. immitis in both alive and necropsied dogs was 22.49% (38/169). Out of 150 alive dogs, 29 (19.3%) were positive for D. immitis microfilariae. The prevalence of the infection varied according to the technique used, ranging from 16.0 to 19.3% based on direct blood smear microscopy and modified Knott's technique, respectively. The infection rate was significantly higher (p < 0.05) in dogs aging more than 3 years. A positive correlation was observed between SGPT and SGOT and the presence of microfilariae (p < 0.05). Among the 19 dead stray dogs, 9 animals showed adult D. immitis nematodes. CONCLUSION Results of this survey account for the presence of D. immitis in stray dogs from Nepal, thus supporting the existence of a local transmission cycle of diroflariosis in the region. Further investigations are warranted to accurately define the prevalence of the infection in the canine population and to undertake appropriate control measures to reduce the burden on the infection in dogs and, accordingly, the risk of transmission to humans.

Abstract
Scientific research can act as the 'bedrock for development' which can provide a solid foundation for the overall socioeconomic transformation in a country through invention and innovation. The inclusion of seven groups of Nepalese monuments in the United Nations Educational, Scientific and Cultural Organization (UNESCO)'s world heritage sites provides evidence of the richness in architecture and civil engineering in the country, which also show how Nepal was influenced by arts and religious philosophy. The government of Nepal (GoN) has established different scientific departments, universities, and research institutions, and has tried to emphasize the application of science and research for the development of the nation. These institutions, however, have inadequate resources, exist in a poor academic and research environment and are subject to overt political influence. Despite these various problems, a variety of pioneer research and development activities have been conducted, which show positive rays of hope. This review presents history, current situation, progress and future perspective for scientific research and development in Nepal.

Abstract
Rabies is a global problem, but the burden is higher in less developed or developing countries of Asia and Africa. In Nepal, rabies is reported to kill around 500 animals and up to 32 human beings in recent years, with possible under-reporting of cases and deaths. As a prophylactic measure, around 30,000 livestock and 300,000 humans get vaccinated each year in Nepal. This review summarizes the past, present and future perspectives of rabies control and prevention in Nepal. The global strategic plan of World Health Organization (WHO) aims to bring human deaths from dog-transmitted rabies to zero by 2030. To achieve this goal of ‘Zero by 30’, the concerned governmental and non-governmental agencies in Nepal should work together using the One Health concept. Rabies is caused by Lyssa virus that is responsible for deaths of 55,000 people annually across the world. Dogs are responsible for 95% of rabies cases around the globe and 99% in endemic regions. Asia has the highest burden of rabies and India alone accounts for around 35% of world rabies cases. In Nepal, less than 35 people have died each year due to rabies. One health approach is mandatory to end dog mediated rabies by the year 2030.

Abstract
Viruses are having great time as they seem to have bogged humans down. Severe acute respiratory syndrome (SARS), Middle East respiratory syndrome (MERS), and novel coronavirus (COVID-19) are the three major coronaviruses of present-day global human and animal health concern. COVID-19 caused by SARS-CoV-2 is identified as the newest disease, presumably of bat origin. Different theories on the evolution of viruses are in circulation, yet there is no denying the fact that the animal source is the skeleton. The whole world is witnessing the terror of the COVID-19 pandemic that is following the same path of SARS and MERS, and seems to be more severe. In addition to humans, several species of animals are reported to have been infected with these life-threatening viruses. The possible routes of transmission and their zoonotic potentialities are the subjects of intense research. This review article aims to overview the link of all these three deadly coronaviruses among animals along with their phylogenic evolution and cross-species transmission. This is essential since animals as pets or food are said to pose some risk, and their better understanding is a must in order to prepare a possible plan for future havoc in both human and animal health. Although COVID-19 is causing a human health hazard globally, its reporting in animals are limited compared to SARS and MERS. Non-human primates and carnivores are most susceptible to SARS-coronavirus and SARS-CoV-2, respectively, whereas the dromedary camel is susceptible to MERS-coronavirus. Phylogenetically, the trio viruses are reported to have originated from bats and have special capacity to undergo mutation and genomic recombination in order to infect humans through its reservoir or replication host. However, it is difficult to analyze how the genomic pattern of coronaviruses occurs. Thus, increased possibility of new virus-variants infecting humans and animals in the upcoming days seems to be the biggest challenge for the future of the world. One health approach is portrayed as our best way ahead, and understanding the animal dimension will go a long way in formulating such preparedness plans.

Abstract
One Health (OH) is a collaborative effort to attain optimal health for people, animals and the environment. The concept of OH is still in its infancy in Nepal but is increasingly growing. The Government of Nepal (GoN) has taken some initiatives to tackle burgeoning problems such as antimicrobial resistance, highly pathogenic avian influenza and rabies using OH approach but there are several challenges at the level of implementation. Few non-governmental organizations support GoN to promote an OH approach. The major bottlenecks in implementing OH in Nepal include poor organizational structure to support OH, absence of a legal framework to implement OH, poor coordination among different governmental agencies, insufficient technical expertise, poor data sharing mechanism across sectors, limited budget and poor understanding at political level. We encourage GoN to address these gaps and prioritize the health problems where OH approach would give the best outcome. Institutional and legal frameworks need to be created to effectively implement an OH approach in Nepal. Increasing awareness among policy makers including political leadership and increasing regular government budget for OH activities would be helpful to promote OH in Nepal.

Abstract
Background Leptospirosis is a zoonotic disease with worldwide distribution. It affects both humans and animals. Dogs may serve as a sentinel as well as a potential carrier for Leptospira infection in human. This study was conducted with the aim of investigating the sero-prevalence of leptospirosis, and differentiation in blood parameters in positive and negative cases of dogs. Methods A cross-sectional study was carried out from August 2016 to December 2016 in Kathmandu valley. A total of 70 blood samples were collected from street dogs and tested against Leptospira infection using Immunocomb Canine Leptospira Antibody Test Kit. Results Out of 70 blood samples tested, eight samples (11.4%) were positive. The average mean and SD of total leucocyte count of positive and negative cases were 79 750±12 090/mm3 and 11 026.98±4316.742/mm3, respectively. Levels of blood parameters (total leukocyte count (TLC), blood glucose, serum glutamic pyruvic transaminase (SGPT), serum glutamic oxaloacetic transaminase (SGOT), and calcium and phosphorus) were found to be increased, and significant between positive and negative cases p<0.05, where blood urea and protein remained constant and non-significant. Conclusion Detection of Leptospira antibody in non-vaccinated dogs indicates a significant threat to human population and demand unique strategic action plan for the control and prevention of disease.

Abstract
Foot and Mouth Disease (FMD) is endemic in Nepal and causes substantial economic losses in the livestock industry. The goal of this study was to perform an epidemiological analysis of FMD outbreaks reported to the Veterinary Epidemiology Center, Tripureshwor, Nepal during 2010-2015, in order to strengthen the National FMD Control Program. These current data were considered in the context of historical data on FMD virus (FMDV) serotypes detected in the country between 1965 and 2015. During 2010-2015, a total of 1333 livestock holdings reported FMD outbreaks in Nepal. On average, 71.2 animals were affected in each outbreak, with a case fatality rate of 3.6%. FMD was reported throughout the country, and the proportion of affected holdings was not significantly among eco-zones, regions, or species. The Hill eco-zone had the highest number of holdings affected (782), followed by Mountain (304), and Terai (247). When analysed by the developmental region, the Western (381) and Central (368) Developmental Regions had the highest numbers of holdings affected. Cattle were the most frequently affected species (39%), followed by buffalo (33%), and goats (19%). FMD occurred throughout the year, with peaks in winter (December/January) and in the pre-monsoon period (April/May). Between 1965 and 2015 FMDV serotype O had the highest prevalence (81%), followed by Asia-1 (11%), A (6%), and C (2%). Serotype C was not detected after 1996, and only serotype O was reported after 2011. These descriptive analyses provide critical landmarks to establish baselines, and document early progress of the ongoing Progressive Control Pathway of FMD (PCP-FMD) which could be useful in Nepal and other South Asian nations.

Abstract
Brucellosis is an abortifacient zoonotic disease that remains prominent in third world countries like Nepal. Brucellosis poses a public health concern, because its incidence in livestock can present substantial economic and health burdens for herders and health professionals. Several cases of bovine and human brucellosis have been reported and the prevalence is higher among livestock than among humans in Nepal. Lack of awareness, unhealthy food habit, traditional husbandry practices, and a lack of surveillance and immunization have been the major factors in maintaining a vicious cycle of propagation of the disease in human and animals. The aim of this paper is to evaluate the current status of the disease, the mechanism of infection, and pathogenesis, its zoonotic potential, diagnostic advances, treatment regimens, and the preventive measures that can be adopted in managing human brucellosis in under-developed countries such as Nepal.

OBJECTIVES The aim of this paper is to evaluate the current status of the disease, the mechanism of infection, and pathogenesis, its zoonotic potential, diagnostic advances, treatment regimens, and the preventive measures that can be adopted in managing human brucellosis in under-developed countries such as Nepal. METHODS We performed a systematic review of all the available literture through Google Scholar, PubMed, Gideon Informatics, World Health Organization and other legitimate sources. Other secondary informations were collected from the government agencies such as department of livestock services and Ministry of Health. The obtained information was then re-analysed and summarized. RESULTS Few publications have addressed brucellosis in Nepal and most of those publications have focused on bovine brucellosis with sparse information available on brucellosis in humans and small ruminants. Brucella abortus is the most predominant causative agent followed by B. suis. B. abortus is predominant in cattle accounting for a substantial portion of bovine abortion in the country. Lack of awareness, unhealthy food habit, traditional husbandry practices, and a lack of surveillance and immunization have been the major factors in maintaining a vicious cycle of propagation of the disease in human and animals. Unfortunately, nothing has been done to identify the species of Brucella at the biovar level. CONCLUSIONS Although brucellosis has been reported to be endemic in Nepal, neither the distribution nor the economic and public health impact of this disease is well characterized. Robust and well-designed nationwide survey is warranted to assess the prevalence and distribution of disease in livestock and humans. Such data would facilitate the design of appropriate control programmes.

Abstract
AIM The aim of the study was to document the indigenous ethno-botanical knowledge of the transhumant nomads of Mustang, Nepal, a representative settlement in the Himalayan highland. METHODOLOGY A study was carried out during a direct field visit to collect plants, consisting of a semi-structured questionnaire and personal interviews. Both fresh and dried herbs, plants parts, and fungus were collected as far as possible. RESULTS The present study identified 51 medicinal plants and 2 funguses that were used for 47 different ailments in the medicinal practices of the nomadic tribes of Lower Mustang, Nepal. Most of the medicines were prepared as juice (22.64%) or powder (49.05%) and administered orally. Roots (23%) and leaves (28%) were the most frequently used parts of the plants while prayer-laced ties were commonly applied in sheds and housing areas. CONCLUSION This study has shown that the transhumant pastoralist nomadic communities have their own traditional ethno-botanical medicines that remain cost effective and the method of choice for management of health disorders and is passed down through oral traditions under the guidance of an herbal practitioner. There is a need for such practices to be scientifically validated, with respect and inclusion into sustainable veterinary medicine to support these remotely located communities.

Abstract
Rapid reduction in natural resources as a consequence to the expanded urbanization, global warming and reduced natural habitat posed a considerable threat to the sustainability of traditional medicine. Being completely dependent upon natural resources like herbs, minerals and animal products, traditional medicine would possibly rank first in order of extinction of heritage if an alternative way is not considered well in time. In reference to the use of animal products, Ayurveda presents some unique examples where animals are used without causing harm to them and so without posing a threat to their existence. In the current context, when natural resources are facing a threat to their existence, a revisit to these ideas may give us a new insight to refine our look at natural resources used in traditional medicine.

Abstract
The usefulness of acupuncture (AP) as a complementary and/or alternative therapy in animals is well established but more research is needed on its clinical efficacy relative to conventional therapy, and on the underlying mechanisms of the effects of AP. Cardiac magnetic resonance imaging (CMRI), an important tool in monitoring cardiovascular diseases, provides a reliable method to monitor the effects of AP on the cardiovascular system. This controlled experiment monitored the effect electro-acupuncture (EA) at bilateral acupoint Neiguan (PC6) on recovery time after ketamine/xylazine cocktail anesthesia in healthy cats. The CMRI data established the basic feline cardiac function index (CFI), including cardiac output and major vessel velocity. To evaluate the effect of EA on the functions of the autonomic nervous and cardiovascular systems, heart rate, respiration rate, electrocardiogram and pulse rate were also measured. Ketamine/xylazine cocktail anesthesia caused a transient hypertension in the cats; EA inhibited this anesthetic-induced hypertension and shortened the post-anesthesia recovery time. Our data support existing knowledge on the cardiovascular benefits of EA at PC6, and also provide strong evidence for the combination of anesthesia and EA to shorten post-anesthesia recovery time and counter the negative effects of anesthetics on cardiac physiology.

Abstract
Nepal the “Shangri-La” in the lap of the Himalayas is gearing up for modern times as it starts rebuilding after a decade of senseless violence and destruction. The nation one of the poorest in the global development index is rich in natural resources and biodiversity. Reports of medicinal plants far exceeding those recorded and reported so far are encouraging and at the same time concerns for medicinal plants under threat as a result of overexploitation are emerging from Nepal. The harsh mountain terrains, lack of industrialization and harnessing potentiality of its areas of strength; water; natural resources and tourism make it poor in per capita income which averages ~ 300 US$, with half the population living under >1$ a day. Nepal is beginning to realize that the way ahead is only possible through the path of Science and Technology (ST). Nepal Academy of Science and Technology formerly known as Royal Academy of Science and Technology organized the fifth national conference held every 4 years that took place in the capital Kathmandu during November 10-12, 2008. The ST initiation event saw the participation of ~ 1400 people representing over 150 organizations from the country and experts from abroad. The theme for the fifth national meet was “Science, Technology and Innovation for Prosperous Nepal”. Complementary and Alternative Medicine (CAM) was an important theme in the event as the realization for the need of ST research focused in CAM for harnessing the chemo diversity potential was univocally approved.

Abstract
The aim of this study was to investigate the effects of Ginkgo biloba extract (EGb 761) on male copulatory behavior in rats. EGb 761 (1 mg/ml) induced significant production of testosterone (T) in rat Leydig cells in vitro. Its effects on sexual behavior were then tested in Long-Evans male rats after 7, 14, 21, or 28 days of oral gavage of vehicle (distilled water) or EGb 761 at doses of 10, 50, or 100 mg/kg. Administration of 50 mg/kg of EGb 761 for 28 days and of 100 mg/kg for 14 or 21 days significantly increased intromission frequency compared to controls on the same day. An increase in ejaculation frequency was seen after treatment with 50 mg/kg of EGb 761 for 14, 21, or 28 days when compared to either the control group on the same day or the same group on day 0. A reduction in ejaculation latency was only seen after administration of 50 mg/kg of EGb 761 for 14 days compared to the vehicle-treated group. After treatment for 28 days, no significant difference was seen in mount latency, intromission latency, serum T levels, reproductive organ weight, sperm number, or levels of the metabolite of dopamine, 3,4-dihydroxyphenylacetic acid in the brain with any dose of EGb 761, but significantly reduced serum prolactin levels and increased dopamine levels in the medial preoptic area and arcuate nucleus were seen at the dose of 50 mg/kg. These findings show that EGb 761 (especially at the dose of 50 mg/kg) enhances the copulatory behavior of male rats and suggest that the dopaminergic system, which regulates prolactin secretion, may be involved in the facilitatory effect of EGb 761.

Abstract
Saliva steroid assay is an upcoming area of research, with much potential for growth and progress. Expensive, varying results with commercial kits and the disadvantages of radioimmunoassay have forced researchers to develop their own system of enzyme immunoassay (EIA). A modification from our established EIA system was used to develop a saliva cortisol (F) assay system. The system sensitivity (>90pg/mL) was checked by various experiments, including comparison of data with a commercial kit obtained from Salimetrics. The assay system was employed to investigate the saliva F level in a young Taiwanese population, and compared with the total and free serum levels of F.

Abstract
Of all the countries in the world, why did you choose Taiwan to pursue your study? It is a question that I (comments of the first author) have answered a thousand times. My first visit to a laboratory at National Taiwan University opened my eyes to the possibilities of herbal medicine research, especially in the area of veterinary medicine. It became my ambition to link the knowledge of Traditional Chinese Medicine (TCM) and Ayurveda from the Indian subcontinent and their integration with other systems of medicine, including Western medicine (WM), to achieve the concept of Sustainable Medicine, firstly for animals and then for humans. The Ministry of Economic Affairs (MOEA) has implemented a technology development program to quickly establish the key technologies, and this is a moment of opportunity for Taiwan's traditional herbal medicine industry to upgrade and transform itself. This paper, initially intended to be a student's narration, has evolved into a multi-author treatise on the present state and likely future scenario of herbal medicine research in Taiwan.

Abstract
Betel quid (BQ) is a favorite chewing item among many communities in different parts of Asia where it is popular by different names. BQ is a unique combination of nut or fruit from the Areca catechu Linn. (AN) tree, leaf from the Piper betle Linn. (BL) vine, slaked lime, paste of bark from the Acacia catechu tree and other spices. AN has been used successfully in various traditional medicines by different civilizations over several ages. Initially condemned by the medical communities for its health hazards, identification and application of potent pharmacologically bioactive compounds from different constituents of BQ have rekindled growing interest in related investigations. Curious about the stimulating role of BQ, we investigated the potential steroidogenic activity of hot water extract from BQ and its constituents and arecoline on testosterone producing ability in an in vitro experiment. Enzyme dissociated interstitial cells from adult mouse testes (ICR strain) were cultured with/without different doses of the extracts and the level of testosterone produced was assayed by an enzyme immunoassay (EIA) technique. It was found that at lower doses of arecoline, AN and BL extracts had significantly stimulated testosterone production over the basal level (p < 0.05). BQ extract, on the other hand, did not show any significant effect on testosterone production. Combinations of arecoline at low doses with 10 ng/ml ovine leutinizing hormone (oLH) showed increases in testosterone produced, while cyclic adenosine monophosphate (cAMP) co-culture showed dose-related inhibition. Our current finding hints at the possible dose-dependent dualistic role of AN and BL extracts and arecoline for testosterone production employing possible non-cAMP-dependent pathway of steroidogenesis. However, the identity of the active compounds besides arecoline and the exact mechanism involved remains to be further investigated.

Abstract
Sustainability aims to harmonise life on Earth without compromising the essential natural resources that should be the birthright of future generations. 'Sustainable medicine' (SM) is just one component of the wide range of possible sustainable approaches to peaceful co-existence. Sustainable medicine envisions an uncomplicated system of maintaining the health of people and animals, both now and for many years to come. This type of medicine is based on ancient wisdom, knowledge and healing arts, combined with the advantages and technical achievements of modern science and other areas of medicine; it is an integrated approach to preventive, safe and affordable healing. The term sustainable medicine also implies that the main therapeutic materials used in the course of practising this type of medicine can be replaced or replenished with minimal environmental damage after harvesting. The aim of sustainable medicine is to maintain the balance of nature, allowing an estimated 7 to 100 million species of life forms to co-exist and reproduce, and to sustain the long-term future of this planet. The world is in the midst of an environmental crisis: anthropogenic environmental damage in the last century was greater than in any previous century. One of the major concerns is the misuse of medicines, and the resulting immune depletion in people and animals. Many traditional medical systems have taught that appropriate adaptation by, and of, an effective defence system is the key to health and survival. This is only possible if priority is given to a preventive rather than a curative approach to health care; the very same approach that is advocated by proponents of SM: an approach based on proper diagnosis and the use of personalised, tailor-made medicine. The authors propose SM (the combination of the advantages of modern, traditional and complementary medical systems) as the best approach to providing better health care services for people and animals. The article presents a brief history of traditional medicines and outlines strategies for developing SM. The authors highlight some important factors in the development of SM in animal health care and attempt to encourage veterinarians to adopt a sustainable approach to treating animals.

Abstract
More than 155 participants from 25 countries attended the 30th Annual IVAS Congress, September 8–11, 2004 in Oostende, Belgium. The focus was on veterinary acupuncture (AP) and immunology, and the event was sponsored by the International Veterinary Acupuncture Society (IVAS). IVAS is a non-profit organization dedicated to promoting excellence in the practice of veterinary AP as an integral part of the total veterinary health care delivery system. The Society endeavors to establish uniformly high standards of veterinary AP through its educational programs and accreditation examination. IVAS seeks to integrate veterinary AP and the practice of Western veterinary science, while also noting that the science of veterinary AP does not overlook allied health systems, such as homeopathy, herbology, nutrition, chiropractic, kinesiology, etc. (www.ivas.org).

Abstract
The needles of ponderosa pine (Pinus ponderosa Laws.) were reported to induce abortions when fed to late-term pregnant beef cows in North America. An in vivo study of pregnant cows suggested that isocupressic acid (IA) was the main abortifacient isolated from needles and bark of the pine. However, the mechanism of abortifacient activity of IA is not clear yet. In a pregnant cow, the corpus luteum of the ovary helps the maintenance of pregnancy by its progesterone production. This study involved the IA extracted from the root of the Taiwan cypress (Juniperus formosana) and used a frozen-thawed bovine luteal cell culture system to investigate the action of IA on progesterone production. Thawed bovine luteal cells (1 x 10(5) cells/ml/well) in M199 medium were cultured in 24-well culture plates at 37 degrees C in a 5% CO2 incubator. Ten ml of tested drugs, IA at 1 to 1000 ng/ml and/or ovine luteinizing hormone (oLH) at 1 to 100 ng/microl or 8-bromo-cyclic adenosine monophosphate (8-Br-cAMP) with 0.1-10 mM, were added into each well. After 4 hours of incubation, the media were harvested and assayed for progesterone by an enzyme immunoassay. Progesterone production from cells was the indicator used to evaluate the action of IA. All tested doses of IA significantly inhibited progesterone production in both basal and oLH stimulating conditions. Also those dosages inhibited cyclic adenosine-3',5'- monophosphate (cAMP) stimulation, suggesting a post-cAMP mechanism is involved in the IA action. We concluded that IA can induce pregnant cows to abort partly through blocking luteal function and may be identified as a new abortifacient chemical.
