Action of Carduus marianus 6cH on Hepatopathy and Gallstone in Ambystoma mexicanum (Axolotl): Case Report

BACKGROUND

 Carduus marianus is a Mediterranean plant used for treating liver diseases. One of its properties is that it inhibits fat peroxidation, which can contribute toward the prevention of metabolites that are harmful to the liver.

OBJECTIVE

 The aim of this study was to describe the treatment of fatty liver disease in an axolotl (Ambystoma mexicanum).

METHODS

 An approximately 6-year-old female specimen of A. mexicanum, of length 21 cm and weight 153 g, presented edema in the rostral region and inappetence. Ultrasound showed hepatopathy and a gallbladder stone. A globule of C. marianus 6cH was diluted in 30 mL distilled water and administered in spray form over the animal twice a day.

RESULTS

 Twenty days after the beginning of the treatment, improvement of the facial edema and return of appetite were observed. Ultrasound showed improvement in the appearance of the liver and reduction in the size of the gallstone. The Modified Naranjo Criteria for Homeopathy score was +9 in this case, thus suggesting a causal relationship between the use of homeopathic medicine and the clinical outcome.

CONCLUSION

 C. marianus 6cH appeared to be effective in treating fatty liver disease and gallstone in this specimen of A. mexicanum.

Dilated cardiomyopathy phenotype in Callithrix penicillata (E. Geoffroy, 1812): Case report

Dilated cardiomyopathy (DCM) is a disease of the heart muscle diagnosed by alterations resulting from ventricular systolic dysfunction with enlargement of the heart chambers, which is still underdiagnosed in non-human primates. This report is the first case of the DCM phenotype diagnosed by echocardiography and confirmed by necropsy in Callithrix penicillata.

First report of spontaneous hepatic fibrosarcoma in a white-tufted marmoset (Callithrix jacchus) kept in captivity

Reports of sarcomas in nonhuman primates are scarce and, specifically, primary hepatic sarcomas are rare, as in humans. This is the first report of an aggressive hepatic fibrosarcoma in a young adult Callithrix jacchus. The final postmortem diagnosis was obtained by means of immunohistochemical analysis, which confirmed the tumor histogenesis.

Action of Folliculinum 6cH on Folliculogenesis in the Snake Python Regius (Shaw, 1802) - Two Case Reports

BACKGROUND

Folliculinum is a homeopathic sarcode medication that is mainly used for regulating the estrous cycle and reproductive function. In snakes, it is common to observe low frequencies of reproduction. Ovulation is related to follicular size and morphology, and follicle homogeneity may indicate the absence of problems such as dystocia (egg retention) or follicular stasis.

OBJECTIVE

The objective of the present study was to report on follicular stage changes in two ball pythons, Python regius (Shaw, 1802), which were treated using Folliculinum 6cH in a zoological park setting.

METHODS

Two female pythons - one weighing 2.8 kg, the other weighing 2.5 kg, and neither with a history of reproduction - were examined by ultrasound to enable viewing of ovarian follicles in different phases and sizes. Folliculinum 6cH, two globules diluted in 200 mL of water, was administered, targeted to the eyes and nostril regions.

RESULTS

Even given the slow metabolism of reptiles, ultrasound revealed an improvement in follicle homogeneity between 6 and 15 days after the start of homeopathy in both snakes; there was also improved weight gain in both animals. The MOdified NARanjo Criteria for Homeopathy (MONARCH) score was +8 in each of the cases, suggesting a causal relationship between the use of homeopathic medicine and clinical outcome.

CONCLUSION

Folliculinum 6cH may have promoted stabilization of follicle size and enabled folliculogenesis in two ball pythons.

Evaluation of the Effects of Administering Ultradiluted Avena sativa and Echinacea angustifolia on the Hematological Parameters of Magellanic penguins (Spheniscus magellanicus) during the Reproductive Period

BACKGROUND AND AIMS

Penguins are seabirds that manifest physiological and immunological alterations during the reproductive season. The objectives of this study were to evaluate the laboratory parameters of male and female Magellanic penguins and to determine the penguins' hematological response to homeopathic medicines during that reproductive period.

METHODS

Penguins (N = 18), kept under human care in a zoological park setting, were evaluated during the reproductive period and were divided randomly into two groups: a group subjected to treatment with Echinacea angustifolia 6cH and Avena sativa 6cH (N = 8; four breeding couples), and a placebo control group (N = 10; five breeding couples). The investigators were blinded to treatment allocation. Two-way ANOVA was performed to determine whether the experimental group (control or verum) and the sex of the animal had any significant effect on the variation of each hematological parameter between the samples. One-way ANOVA was performed on hematological parameters for which the sex did not present a significant effect. The significance level was p ≤0.05.

RESULTS

Significant effects were seen regarding the following: mean corpuscular volume (MCV), in which the verum group showed an increase (29.78 ± 52.95 fL) while the control group showed stability/reduction (-3.08 ± 46.36 fL) (p = 0.049); proportion of heterophils, in which the verum group showed a less marked increase (8.38 ± 12.53%) than that of the control group (18.00 ± 9.37%) (p = 0.010); lymphocyte concentration, in which the verum group showed less marked reduction (-4.39 ± 2.21 × 109 cells/L) than that of the control group (-1.56 ± 2.76 × 109 cells/L) (p = 0.001); and proportion of lymphocytes, in which the verum group showed a less marked reduction (-6.75 ± 10.35%) than that of the control group (-17.3 ± 8.73%) (p = 0.002).

CONCLUSION

Comparison of samples collected before and during the reproductive period showed that, regardless of group allocation, there were differences in the effects on MCV, heterophils and lymphocytes. Treatment with Echinacea angustifolia and Avena sativa resulted in maintenance of lymphocyte levels in Magellanic penguins during the breeding period, thus aiding these birds' immunity.

First report on herpesvirus in black-fronted titi (Callicebus nigrifrons) kept under human care

Keeping Neotropical primates in captivity puts them at great risk of illness because of their susceptibility to human herpesvirus. This is the first report on herpesvirus in Callicebus nigrifrons that developed clinical disease and was confirmed by immunohistochemical and RT-PCR. Diagnosis and prevention are essential for the conservation of species.

Use of Homeopathic Arnica montana 30cH for Postoperative Analgesia in Female Dogs Undergoing Elective Ovariohysterectomy

BACKGROUND

 Ovariohysterectomy (OH) is one of the most frequent elective surgical procedures in routine veterinary practice. Arnica montana is a well-known medicine in phytotherapy, with proven analgesic, anti-inflammatory, antiseptic, healing, antioxidant and immunomodulatory activity. However, there is still a shortage of studies on the action and effects of the homeopathic formulation of the medicine on animals. The aim of this study was to evaluate analgesia with Arnica montana 30cH during the postoperative period after elective OH.

METHODS

 Thirty healthy female dogs, aged 1 to 3 years, weighing 7 to 14 kg, were selected at the Veterinary Hospital in Campo Mourão, Paraná, Brazil. The dogs underwent the surgical procedure with an anaesthetic protocol and analgesia that had the aim of maintaining the patient's wellbeing. After the procedure, they were randomly divided into three groups of 10. One group received Arnica montana 30cH; another received 5% hydroalcoholic solution; and the third group, 0.9% NaCl saline solution. All animals received four drops of the respective solution sublingually and under blinded conditions, every 10 minutes for 1 hour, after the inhalational anaesthetic had been withdrawn. The Glasgow Composite Measure Pain Scale was used to analyse the effect of therapy. Analysis of variance (ANOVA) followed by the Tukey test was used to evaluate the test data. Statistical differences were deemed significant when p ≤0.05.

RESULTS

 The Arnica montana 30cH group maintained analgesia on average for 17.8 ± 3.6 hours, whilst the hydroalcoholic solution group did so for 5.1 ± 1.2 hours and the saline solution group for 4.1 ± 0.9 hours (p ≤0.05).

CONCLUSION

 These data demonstrate that Arnica montana 30cH presented a more significant analgesic effect than the control groups, thus indicating its potential for postoperative analgesia in dogs undergoing OH.

Evaluation of the Efficacy of Crataegus oxyacantha in Dogs with Early-Stage Heart Failure

BACKGROUND

Myxomatous mitral valve disease (MMVD) is the most common cardiopathy in middle-aged dogs. When the dog is asymptomatic and has an enlarged left atrium, treatment is beneficial; however, some allopathic drugs are very costly and may produce side effects. To extend the duration of this asymptomatic phase, complementary therapies such as herbal medicine and homeopathy are available. Although herbal therapy with extract of Crataegus oxyacantha is beneficial, there is a risk of adverse reactions-unlike with homeopathy, where the risk is minimized with the administration of ultra-diluted doses.

OBJECTIVE

This study evaluated the efficacy of Crataegus oxyacantha, as mother tincture (MT) and in 6 cH homeopathic formulation, in treating the initial phase of heart failure due to MMVD in a veterinary clinic setting.

METHODS

A total of 30 dogs with MMVD, 7 years or older and weighing up to 10 kg, were randomized into three groups as follows: Crataegus 6 cH, Crataegus MT, and hydroalcoholic solution (placebo). Animals were evaluated through echocardiography parameters, laboratory blood tests, and systolic blood pressure (SBP) measurements at 30, 60, 90, and 120 days after initiation of therapy, for statistical analysis and monitoring of the blinded study.

RESULTS

Patients who received Crataegus 6 cH showed a reduction in SBP 60 days after treatment, while those receiving Crataegus MT exhibited a reduction 90 days after the therapy was initiated. There was a significant linear regression when evaluating the effect of treatment with Crataegus 6 cH on SBP measurements over the evaluation intervals (linear equation: SBP = 176.57 mm Hg - 0.21x, where x represents days of treatment). There was an increase in both fractional shortening and isovolumetric relaxation time for those patients receiving the homeopathic formulation.

CONCLUSIONS

Therapy with Crataegus was beneficial for hypertensive and cardiopathic dogs with MMVD, extending the duration of the asymptomatic phase. The reduction in SBP occurred more swiftly in the 6 cH group than in the MT-treated dogs.
