The cysts of Sarcocystis grueneri were detected and characterized from the cardiac muscles of the Korean water deer (Hydropotes inermis argyropus). Of the 38 heart muscle samples examined by light microscopy, 10 were found infected with the cysts of Sarcocystis sp. The cysts appeared oval to spherical shape and measured 110–380 μm in length and 90–170 μm in width. A phylogenetic tree of the 18S rRNA sequences (1.5 kb) revealed a close relationship of the infected cysts to genus Sarcocystis. The 18S rRNA sequence of the infected cysts showed 100% identity to S. grueneri and 97% to S. capracanis. Here, we first report the S. grueneri infections in the Korean water deer.

Deer is valuable all over the body,which is rich in nutritional value and medicinal value. Deer breeding and processing are very advanced in North America and New Zealand where many related standards have been published. The development of Chinese deer industry lack standard and normal management,neither standards' number nor coverage area formed complete frame structure. The international standards like Panax ginseng and P. notoginseng were more lacked. This paper makes a classification statistics on standardization organizations at home and abroad,foreign standards,Chinese national standards,industry standards,local standards and enterprise standards. The classes,contents,ages,implementation and promotion and demonstration area construction of standards were compared and analyzed. We found Chinese deer industry standards were deficient in coverage,uniformity,innovation,repeatability and support. And we give advises for the construction of industry quality standard system,organizational mobility and ideology of consumers,hoping to boost the standard construction and promote international competitiveness of Chinese deer industry.

The differences and the variations of chondroitin sulfate content in different parts of Cervi Cornu Pantotrichum(CCP) with different processing methods were investigated. The chondroitin sulfate from velvet was extracted by dilute alkali-concentrated salt method. Next， the chondroitin sulfate was digested by chondroitinase ABC.The contents of total chondroitin sulfate and chondroitin sulfate A， B and C in the samples were determined by high performance liquid chromatography(HPLC).The content of chondroitin sulfate in wax，powder，gauze，bone slices of CCP with freeze-drying processing is 14.13，11.99，1.74，0.32 g·kg⁻¹， respectively. The content of chondroitin sulfate in wax，powder，gauze，bone slices of CCP with boiling processing is 10.71，8.97，2.21，1.40 g·kg⁻¹， respectively. The content of chondroitin sulfate in wax，powder，gauze，bone slices of CCP without blood is 12.47，9.47，2.64，0.07 g·kg⁻¹， respectively. And the content of chondroitin sulfate in wax，powder，gauze，bone slices of CCP with blood is 8.22，4.39，0.87，0.28 g·kg⁻¹ respectively. The results indicated that the chondroitin sulfate content in different processing methods was significantly different.The content of chondroitin sulfate in CCP with freeze-drying is higher than that in CCP with boiling processing.The content of chondroitin sulfate in CCP without blood is higher than that in CCP with blood. The chondroitin sulfate content in differerent paris of the velvet with the same processing methods was arranged from high to low as： wax slices， powder， gauze slices， bone slices.

Hypoderma spp. larvae cause subcutaneous myiasis in several animal species. The objective of the present investigation was to identify and characterize morphologically and molecularly the larvae of Hypoderma spp. collected from cattle (Bos taurus taurus) and red deer (Cervus elaphus) in the district of Castelo Branco, Portugal. For this purpose, a total of 8 larvae were collected from cattle (n=2) and red deer (n=6). After morphological identification of Hypoderma spp. larvae, molecular characterization was based on PCR-RFLP and mitochondrial CO1 gene sequence analysis. All larvae were morphologically characterized as the third instar larvae (L3) of H. actaeon. Two restriction enzymes were used for molecular identification of the larvae. TaqI restriction enzyme was not able to cut H. actaeon. However, MboII restriction enzyme differentiated Hypoderma species showing 210 and 450 bp bands in H. actaeon. Furthermore, according to the alignment of the mt-CO1 gene sequences of Hypoderma species and to PCR-RFLP findings, all the identified Hypoderma larvae were confirmed as H. actaeon. This is the first report of identification of Hypoderma spp. (Diptera; Oestridae) from cattle and red deer in Portugal, based on morphological and molecular analyses.

OBJECTIVETo determine the contents of amino acids in Cornu Cervi Pantotrichum of different specifications for controlling the quality.

METHODThe contents of 18 kinds of amino acids were determined by amino acid analyzer.

RESULTThe correlation coefficients of 18 kinds of amino acids were all greater than 0.997, the average recovery were all between 99.1%-108.1% with RSDs less than 2.0%. All Cornu Cervi Pantotrichum samples of 29 different specifications contained 17 kinds of amino acids and 7 kinds of essential amino acids. The content of total amino acids in wax slices is relative higher. The content in first born antlers is higher than that in reborn antlers.

CONCLUSIONThis method is suitable for the determination of amino acids in Cornu Cervi Pantotrichum, it provides good reference for the quality control of Cornu Cervi Pantotrichum.

In this study, we analyzed the composition and content of 25 free amino acids in 32 batches of different forms of Cervi Cornu Pantotrichum(CCP; one-branched, two-branched, and three-branched) from 15 producing areas. The clustering analysis and orthogonal partial least squares discriminant analysis(OPLS-DA) were performed based on the content of 25 free amino acids. Potential differential metabolites were identified based on VIP value. The results showed that there were 25 free amino acids in CCP, and the average content of essential, non-essential, and total amino acids was 6.13, 32.99, and 39.12 mg·g~(-1), respectively. The clustering analysis and OPLS-DA demonstrated that 25 free amino acids had different content among the three forms of CCP, of which two-branched CCP samples were separately gathered into a group. Five differential components, including glutamic acid, tryptophan, ornithine, γ-aminobutyric acid, and hydroxylysine, were screened out as potential quality markers for the identification of different forms of CCP. This study provides a theoretical basis for the quality evaluation, processing, and utilization of different forms of CCP.

The present study comprehensively compared the content of chondroitin sulfate in Cervi Cornu Pantotrichum(CCP) and Cervi Cornu(CC) of different specifications and explored the feasibility of chondroitin sulfate as an indicator to distinguish between CCP and CC. Twenty-two batches of CCP of different specifications(two-branched velvet antler and three-branched velvet antler) from 15 habitats, CC from 6 habitats, and 60 batches of CCP slices prepared from different parts(wax slices, powder slices, gauze slices, and bone slices) were collected. High-performance liquid chromatography(HPLC) was used to determine chondroitin sulfate content in CCP and CC of different specifications. Cluster analysis was used to classify CCP slices of different specifications. The results showed that CCP contained abundant chondroitin sulfate. The average content of chondroitin sulfate was 2.35 mg·g~(-1) in two-branched velvet antler and 1.79 mg·g~(-1) in three-branched velvet antler, significantly higher than 0.11 mg·g~(-1) in CC. Chondroitin sulfate content in wax slices, powder slices, gauze slices, and bone slices were 7.81, 8.39, 1.33, and 0.54 mg·g~(-1), respectively. Cluster analysis showed that gauze slices and bone slices could be clustered into one category and distinguished from wax slices and powder slices. CCP slices prepared from different parts could be separated well through chondroitin sulfate content. Based on the five principles of Q-marker selection, chondroitin sulfate can be used as a potential Q-marker for the identification of CCP and CC, as well as a potential quality indicator for CCP slices of different specifications(wax slices, powder slices, gauze slices, and bone slices). This research provides data support for CCP quality evaluation.
