Biophoton emission is a common phenomenon in living systems. The intensity of the emission is from a few up to some hundred photons per cm² per second. A coherent field is considered as the source of biophotons and the coherent field plays a important role in biological regulation ^[1-2]. Recently whole body measurements of biophoton emission from human were performed and the reports showed that there is a much high biophoton emission and asymmetric counts between left and right hands from sick peoples demonstrating a potential of this method in medical diagnosis^[3]. To stress the potential, chicks were used as test samples since they are easy to handle.

Up to now few documents could been fount dealing with reemission from livings induced by sunlight. Photon emission were measured from the heads of chicks when they were 7day's to 25day's old. Before measuring the chicks were placed in dark room for 60 min. The other parts of chicks were covered by black paper. The whole chick was gently placed in the measuring dark chamber. The whole process was performed under red light in the dark room. During the whole period of measuring the chicks freely stayed with good food in a large box in the dark room at room temperature.

Low level photon emission and sunlight induced reemission were recorded by the photon counting system BPCL made in the Institute of Biophysics, Chinese Academy of Sciences. The photon counts of PE from chicks were described in the difference of the mean counts between chick and noise compared by statistical t test.

For sunlight induced reemission, the chicks squatted freely under the sunlight for 2min to 30 min with their head towards the sun. After 1 min of the illumination the re-emission were measured.

Comparing with noise level, chicks were showed to give a low level of photon emission from their heads. Figure 1 is a typical measured results which shows that the level of the PE was significant higher than the noise. The level of the PE is related with their age and the healthy situation of the chicks. Figure 2 shows the average result of PE from male and female chicks measured when they were 8 day's to 25day's old. From the figure it can be seen that after 13th day the level was increased. Some problem of the chick can cause a variation of the emission, for instance the emission increased because of the chick catching cold.

After sunlight illumination the whole chick gives a short-life delayed reemission like the brain tissue and cells^[4], and the kinetics of the relaxation did not satisfy exponential law rather a hyperbolic curve like brain tissue and rain cells (Figure 3). However as showed in the figures, the relaxation behavior is more complicate. If the chick stayed under the sun light for a longer time, the RPE appeared with oscillations.

The relaxation behaviors of RPE suggest a coherent electromagnetic field in the chicks. The average counts and the patterns of biophotons from chicks were showed to be various depending upon their situation suggesting that biophotonics may have a good potential in medical diagnoses.

Frohlish^[5] pointed that because of the dipolar properties of cell membrane, because of the H bonds recurring in bio-macromolecules, biological systems were expected to have a branch of longitudinal electric modes in a frequency of 10¹¹ to 10¹² Sec^-1. In biological systems since where always is enough energy available, the supplied energy is stored in a highly ordered fashion but completely thermalized. This high order appears in long-range phase correlation, i.e. in coherence. Because the coherent fields in biological systems maintain in a steady state far away from thermal equilibrium, it is very difficult to measure them directly. Biophoton is a method which can be performed in different levels of living cells, tissues, and even in the whole body. Photon emission from living systems reflects well living states and functions.
