Effects of dietary acetaminophen and vitamin C supplement on serum cortisol and tumor necrosis factor-alpha concentrations in pigs vaccinated with foot-and-mouth disease vaccine

This study evaluated the effect of a combination of acetaminophen and vitamin C (CAV) on reducing serum cortisol and tumor necrosis factor-α (TNF-α) concentrations in piglets vaccinated with foot-and-mouth disease (FMD) vaccine. Piglets were vaccinated with FMD vaccine and treated with CAV at concentrations of 0.0, 0.5, 1.0, and 2.0 kg/ton feed (P-CON, AD-1, AD-2, and AD-3, groups, respectively) for 5 days post-vaccination. Cortisol and TNF-α levels at 5 days post-treatment in the AD-1–3 groups were significantly lower than that in the P-CON group (p < 0.05). There were no significant differences between AD-2 and AD-3 groups and non-vaccinated, non-CAV-treated piglets.

Effect of a mixture of Galla rhois and Cinnamomum cassia extracts on susceptibility to the colonization of Campylobacter jejuni in broiler chickens

The present study evaluated the effects of a mixture of Galla rhois and Cinnamomum cassia extracts (GCE) (1 : 1, w/w) on susceptibility to the colonization of Campylobacter (C.) jejuni in broilers. Eighty two-week-old broilers (n = 20 per group) were used to estimate the efficacy of GCE against C. jejuni infection via drinking water. Antibacterial activity testing revealed that the minimum bactericidal concentration of GCE against C. jejuni was 2.5 mg/mL. Broilers challenged with C. jejuni were administered 0.0 (Non-GCE), 2.5 (GCE-2.5), 5.0 (GCE-5.0) and 10.0 g/L (GCE-10) GCE for 7 days, and the cecal contents were collected from five broilers per group on the 1st, 3rd, 5th, and 7th day post-treatment. On day 3 post-administration, the number of C. jejuni in GCE-5.0 (p < 0.05) and GCE-10 (p < 0.01) was significantly decreased relative to Non-GCE, while on day 7 those in all GCE-treated groups were significantly decreased compared to the Non-GCE group (p < 0.001). Hematological and blood biochemical analysis revealed no significant differences in parameters between the Non-GCE and GCE-treated groups. Based on the results of the present study, GCE was identified as a safe and alternative candidate to suppress C. jejuni colonization in broilers.

Therapeutic effect of oregano essential oil on subclinical bovine mastitis caused by Staphylococcus aureus and Escherichia coli / 대한수의학회지

Oregano (Origanum vulgare) is an aromatic herb belonging to the Lamiaceae family. This study evaluated the therapeutic effect of oregano essential oil (OEO) on clinical bovine mastitis caused by Staphylococcus (S.) aureus and/or Escherichia (E.) coli. Thirty-two quarters from 18 lactating cows with subclinical mastitis were selected from a dairy farm and were divided into 4 groups (8 quarters/group): negative control (CON), positive control (GEN) and two OEO-treated groups (OEO-1 and OEO-2). Each group was intramammarily treated with saline, 10 g/tube of gentamicin ointment, and single and double doses of 0.9 mL OEO ointment twice a day for three days, respectively. After the treatments, physical udder conditions were greatly improved in GEN and OEO groups. In CON group, somatic cell counts (SCCs), number of white blood cells (WBC) and bacteria were increased. However, in OEO groups, SCCs and number of WBC were significantly decreased and S. aureus and E. coli were not detected in milk as compared with those before the treatments as well as GEN group. These results suggest that OEO may be a useful alternative to antibiotics for the control of subclinical bovine mastitis caused by S. aureus and/or E. coli.

Antibacterial and therapeutic effects of a combination of Coptidis rhizoma and Galla rhois extracts in piglets challenged with Campylobacter coli / 대한수의학회지

The antibacterial effects of a combination of Coptidis rhizoma and Galla rhois extracts (CGE) were evaluated in piglets. The minimum bactericidal concentration of CGE was 2.0 mg/mL. Thirty 5-week-old piglets were challenged with Campylobacter (C.) coli after allocation to three different groups, a control and two treatment groups fed with CGE at 2.0 or 4.0 g/kg feed for 7 days. On day 7, C. coli in the feces of the CGE-treated groups were significantly lower than in the control (p < 0.01). These results suggest that CGE can be used to control C. coli in piglets.

Therapeutic effects of combination of Galla rhois extract and Sodium chlorate on Mice infected with Brucella abortus / 동물의과학연구지

This study investigated the therapeutic effects of Galla rhois (GR) ethanol extract (GRE), sodium chlorate (SC), and a combination of GRE and SC on mice infected with Brucella abortus (B. abortus). Mice were infected intraperitoneally with B. abortus and then treated with GRE, SC, and a combination GRE and SC in drinking water for 14 days. Then, serum antibodies were used in a tube agglutination test (TAT), after which the weight and CFUs from each spleen were measured. In addition, histopathological changes in each liver were examined at 14 days post-infection. At 14 days post-infection, negative reactions of serum antibodies in PC (positive control), SCT (SC 1.6 g/L drinking water), GRT (GRE 200 mg/L drinking water), and GST (GRE 200 mg + SC 1.6 g/L drinking water) were 0, 40, 60, and 80%, respectively. The average spleen weight was not significantly different between the groups. At 14 days post-infection, bacterial numbers in all treated groups were significantly lower compared to to that of the PC (GRT and SCT, P<0.05; GST, P<0.001). In terms of histopathological changes in the livers, there were numerous multifocal microgranulomas in the PC, whereas this number successively decreased in the SCT, GRT, and GST groups. Conclusively, a combination of GRE and SC exhibits therapeutic effects on mice infected with B. abortus. These results suggest the potential efficacy of a mixture of GRE and SC in the treatment of brucellosis.

A Case of Tuberculous Panophthalmitis

The tuberculous panophthalmitis is, at present, extremely rare. The authors experienced a case of left tuberculous pailOphthalmitis which is, we imagine, secondary to the minimal active pulmonary tuberculosis of right upper lung of 17 year old girl. Here we briefly report a case of tuberculous panophthalmitis, referring the literature relating to the ocular trberculosis.

Two Cases of Blepharoconjunctivitis Caused by Pubic Lice in a Family

Authors experienced two unusual cases of marginal blepharoconjunctivitis caused by infestion of pubic lice (Phthirus pubis) which were confirmed by slit lamp and light microscopic examination. The patients were forty-three year old Korean female who was infected from her husband and her six year old daughter who had used a same room with her father and mother. We could find pubic lice and ova on the cilia, pubic and axillar regions of female mother patient and cilia, eyeblow and head of her daughter and we could also find the pubic lice and ova on the pubic region of her husband. The prompt improvement of marginal blepharoconjunctivitis of both eyes of them were achieved by cutting of cilia and the use of topical antibiotics.
