Recorded Data

In this article, we attempt to characterize the widespread trade in pet macaques in Vietnam. Data on confiscations as well as surrenders, releases, and individuals housed at rescue centers across Vietnam for 2015–2019 were opportunistically recorded. Data comparisons between Education for Nature Vietnam and three government-run wildlife rescue centers show that at least 1254 cases of macaque keeping occurred during the study period, including a minimum of 32 Assamese macaques (Macaca assamensis), 158 long-tailed macaques (Macaca fascicularis), 291 Northern pig-tailed macaques (Macaca leonina), 65 rhesus macaques (Macaca mulatta), and 110 stump-tailed macaques (Macaca arctoides). A minimum of 423 individuals were confiscated, and at least 490 individual macaques were released. Three semi-structured interviews were conducted with two key Animals Asia (a non-governmental organization) colleagues and their insights are presented. Although we recognize that the data included are limited and can serve only as a baseline for the scale of the macaque pet trade in Vietnam, we believe that they support our concern that the problem is significant and must be addressed. We stress the need for organizations and authorities to work together to better understand the issue. The keeping of macaques as pets is the cause of serious welfare and conservation issues in Vietnam.

Как показали многочисленные исследования, морфологический состав крови зависит от многих факторов, в частности таких, как условия кормления и содержания, возраст подопытных объектов. Однако отсутствуют данные о влиянии биологически активных добавок, таких как хлорелла, «Бактистатин», вода со сниженной концентрацией дейтерия, на гематологические показатели. Приматы обладают высоким анатомо-физиологическим сходством с человеком, поэтому являются незаменимой моделью для воспроизведения различных патологических и токсических состояний человека. Приматы вида макака-резус (Macaca mulatta) являются наиболее удобными и востребованными в работе, широко используются в медико-биологических исследованиях. Для корректной оценки воздействия биологически активных добавок (БАД) на организмы приматов необходимы достоверные сведения о функционировании их кроветворной системы. По результатам нашего исследования в начале опыта количество эритроцитов в крови самцов макак-резусов во всех исследуемых группах было незначительно увеличено относительно физиологической нормы (5–6,2 млн в 1 мм3). Эта закономерность может быть связана со значительным увеличением температуры окружающей среды к моменту начала постановки опыта и не связано с влиянием БАД. Подобная закономерность наблюдалась и по остальным показателям. Так, уровень тромбоцитов в начале эксперимента находился в пределах референтных показателей — от 200 до 400 млрд/л, за исключением самцов 2-й опытной группы. В этой группе наблюдалось незначительное увеличение тромбоцитов — на 17,60 млрд/л, или на 4,40% от максимально допустимых значений референтных показателей. Результаты анализов крови в конце эксперимента показали, что у всех самцов макак-резусов в опытных группах в результате применения БАД количество тромбоцитов приблизилось к физиологической норме. На основании чего можно сделать вывод, что применение суспензии хлореллы, сухой хлореллы, «Бактистатина» и воды с пониженным содержанием дейтерия не приводило к критическому отклонению морфологических показателей крови, что, в свою очередь, даёт возможность применять БАД в рационах кормления обезьян. Blood morphology depends on many factors, particularly feeding, welfare and age of animals. The influence of biologically active supplements (BAS) such as chlorella, “Baktistatin”, and deuterium-depleted water on blood hematological parameters remains open to question. Primates are quite similar to humans in anatomy and physiology and hence are perfect model organisms when testing various pathological and toxic processes. Macaca mulatta is commonly used in research. To analyze the effect of BAS on primate organism the blood test is required. In the beginning of the experiment the concentration of red blood cells (RBC) exceeded slightly physiologically normal state in all the groups (5–6.2 million/mm3). This could possibly be a result of hot conditions. Same was true for other parameters. Platelet concentration was normal and varied within 200–400 billion/l in the beginning, except for the males of the second group. The second group showed insignificant increase in platelet concentration — by 17.60 billion/l, or 4.40%. Feeding male rhesus macaques with BAS optimized platelet concentration. Chlorella suspension, dry chlorella, “Baktistatin”, and deuterium-depleted water had no critical influence on blood morphology and, therefore, could be used in primate diet.

Mean Heart Rate

The circadian timing system (CTS) coordinates an animal's physiology and behavior both internally and with the 24-h day. Previous studies have suggested that the CTS is sensitive to changes in gravity. To examine this question, the expression of the CTS in four juvenile male rhesus macaques (Macaca mulatta) were studied in space. These animals were flown on the Cosmos 2044 and 2229 missions. Activity, heart rate, and axillary and brain (Cosmos 2229) temperatures were recorded. In both flights, the subjects exhibited delays in the phasing of their temperature rhythms and a decrease in mean heart rate compared with ground control studies. These data are in support of other studies that demonstrate that the CTS is sensitive to changes in the gravitational environment. Furthermore, the data also support the concept of a multioscillator organization of the primate CTS due to the differential responses of the rhythms measured.
