چکیده

Intraperitoneal administration of an aqueous extract of rhinoceros horn at 5, 2.5 and 1 g/ml, showed a significant antipyretic effect in rats with hyperthermia induced by subcutaneous injection of terpentine oil. Similar assays with extracts of the horns of saiga antelope, water buffalo and cattle at 5 g/ml also caused a significant drop in fever; however, at 1 g/ml, only saiga antelope horn produced an antipyretic action.

Mechanical limits to maximum weapon size in a giant rhinoceros beetle.

The horns of giant rhinoceros beetles are a classic example of the elaborate morphologies that can result from sexual selection. Theory predicts that sexual traits will evolve to be increasingly exaggerated until survival costs balance the reproductive benefits of further trait elaboration. In Trypoxylus dichotomus, long horns confer a competitive advantage to males, yet previous studies have f...

Analysis of active components of rhinoceros, water buffalo and yak horns using two-dimensional electrophoresis and ethnopharmacological evaluation.

Cornu Rhinoceri Asiatici (rhinoceros horn, RH), Cornu Bubali (water buffalo horn, WBH), and Cornu Bovis grunniens (yak horn, YH) are traditional Chinese medicine (TCM), and have been used in China for thousands of years. In this study, ethnopharmacological experiments were used to evaluate and verify the traditional efficacies of horns. Area under curve (AUC) was used to quantify the pharmacolo...

Variation in cross-sectional horn shape within and among rhinoceros beetle species

Sexual selection has equipped male rhinoceros beetles with large horns on their head and prothorax to aid in battle over access to females. Horns are used to pry and dislodge opponents from resource sites that attract females, so an optimal horn should be able both to withstand the high stresses imposed during fights, and to resist deflection in response to these loads. We examined the cross-se...

Sensilla Density Corresponds to the Regions of the Horn Most Frequently Used During Combat in the Giant Rhinoceros Beetle Trypoxylus dichotomus (Coleoptera: Scarabaeidae: Dynastinae)

In the Japanese horned beetle, Trypoxylus dichotomus (L.), males have a long forked head horn that they use in Þghts with other males over access to sap sites that attract females. Because of the high risk of injury from these contests, males should assess the Þghting potential of their rivals before escalating to direct combat. Indeed, male rhinoceros beetles only escalate to intense Þghting w...

Structure of white rhinoceros (Ceratotherium simum) horn investigated by X-ray computed tomography and histology with implications for growth and external form.

The nasal and frontal horns of two individuals of Ceratotherium simum were examined by x-ray computed tomography (CT scanning), gross observation of sectioned horn, and light microscopy of histological sections of the horn tissue. CT scans of both sets of horns reveal a periodic banding pattern that is evident upon gross observation of sections as darker bands of tissue. The overlap of these ba...
